Dear RRE Ventures Acquisition Corp.

RRE Ventures Acquisition Corp. (Company)

We are lawyers qualified to practise in the Cayman Islands and have acted as Cayman Islands legal advisers to the Company in connection with the Company’s registration statement on Form S-1 to be filed with the Securities and Exchange Commission (Commission) on or about the date of this opinion (Registration Statement), relating to the registration of:

A.	25,000,000 units consisting of:

one Class A Share (as defined below); and

one-third (1/3) of one Warrant (as defined below),

upon the consummation of an initial business combination (Units);

B.	up to 3,750,000 Units, which may be issued upon exercise of an option granted to the underwriter(s) to cover over-allotments, if any, exercisable for a period of 45 days after the closing of the offering (*Over-Allotment Units*);

C.	all Class A Shares and all Warrants issued as part of the Units and the Over-Allotment Units; and

D.	all Class A Shares that may be issued upon the consummation of an initial business combination in respect of the Warrants included in the Units and the Over-Allotment Units,

in each case under the United States Securities Act of 1933, as amended (Securities Act) and pursuant to the terms of the Registration Statement. In this opinion Companies Act means the Companies Act, as amended, of the Cayman Islands.

Each whole warrant entitles the holder thereof to purchase one Class A Share at a price of $11.50 per Class A Share, subject to adjustment as described in the Registration Statement, with only whole warrants being exercisable (Warrants).

The Class A Shares underlying the Units and the Over-Allotment Units are referred to herein as the Unit Shares and the Class A Shares to be issued in accordance with the Warrants are referred to herein as the Warrant Shares.

We are furnishing this opinion as Exhibit 5.2 to the Registration Statement.

For the purposes of giving this opinion, we have examined the Documents (as defined in Schedule 1) which are all the documents which we consider necessary and appropriate for the matters set out in this legal opinion. We have not examined any other documents, official or corporate records or external or internal registers and have not undertaken or been instructed to undertake any further enquiry or due diligence in relation to the transaction which is the subject of this opinion.

In giving this opinion, we have relied upon the assumptions set out in Schedule 2 which we have not independently verified.

Based solely upon the foregoing examinations and assumptions and upon such searches as we have conducted and having regard to legal considerations which we deem relevant, and subject to the qualifications set out in Schedule 3, we are of the opinion that under the laws of the Cayman Islands:

1	Existence and Good Standing. The Company has been duly incorporated as an exempted company with limited liability and is validly existing and in good standing under the laws of the Cayman Islands.

2	Capacity and Power. The delivery of the Registration Statement by the Company and the performance of its obligations thereunder are within the corporate capacity and power of the Company and have been duly authorised and approved by all necessary corporate action of the Company.

3	Authorised Share Capital. Based on our review of the Mem & Arts, the authorised share capital of the Company is US$55,500 divided into:

(a)

500,000,000 Class A ordinary shares of a par value of US$ 0.0001 each (Class A Shares);

(b)

50,000,000 Class B ordinary shares of a par value of US$ 0.0001 each (Class B Shares); and

(c)

5,000,000 Preference shares of a par value of US$ 0.0001 each (Preference Shares).

4	Issued Securities. As of the date of the Certificate of Incumbency (as defined in Schedule 1), the Company has:

(a)

0 Class A Shares;

(b)

9,583,333 Class B Shares; and

(c)

0 Preference Shares,

issued and outstanding.

Unit Shares. The Unit Shares to be issued by the Company as contemplated by the Registration Statementhave been duly authorised and, when allotted, issued and fully paid for in accordance with the Resolutions (as defined in Schedule 1), and when the name of the shareholder is entered in the register of members of the Company (Register of Members), the Unit Shares will be validly issued, allotted, fully paid, and non-assessable and there will be no further obligation on the holder of any of the Unit Shares to make any further payment to the Company in respect of such Unit Shares.

6	Warrant Shares. The Warrant Shares to be issued by the Company as contemplated by the Registration Statement have been duly authorised and, when allotted, issued and fully paid for in accordance with the Resolutions, the terms of the Warrants, and when the name of the

shareholder is entered in the Register of Members, the Warrant Shares will be validly issued, allotted, fully paid, and non-assessable and there will be no further obligation on the holder of any of the Warrant Shares to make any further payment to the Company in respect of such Warrant Shares.

Unit Certificate and Warrant Documents. The execution, delivery and performance of the Unit Certificate and the Warrant Documents (each as defined in Schedule 1) have been authorised by and on behalf of the Company and, once the Unit Certificate and the Warrant Documents have been executed and delivered by any director or officer of the Company, the Unit Certificate and the Warrant Documents will be duly executed and delivered on behalf of the Company and will constitute the legal, valid and binding obligations of the Company enforceable in accordance with their terms.

Cayman Islands Law. The statements under the caption “Taxation” in the prospectus forming part of the Registration Statement, to the extent that they constitute statements of Cayman Islands law, are accurate in all material respects as at the date of this opinion and such statements constitute our opinion.

This opinion is confined to the matters expressly opined on herein and given on the basis of the laws of the Cayman Islands as they are in force and applied by the Cayman Islands courts at the date of this opinion. We have made no investigation of, and express no opinion on, the laws of any other jurisdiction. Except as specifically stated herein, we express no opinion as to matters of fact.

In connection with the above opinion, we hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to our name under the headings, “Risks Relating our Securities”, “Certain Differences in Corporate Law” and “Legal Matters” and elsewhere in the prospectus included in the Registration Statement. In giving such consent, we do not thereby admit that we come within the category of persons whose consent is required under Section 7 of the Securities Act, as amended, or the Rules and Regulations of the Commission thereunder.

This opinion is limited to the matters referred to herein and shall not be construed as extending to any other matter or document not referred to herein.

This opinion shall be construed in accordance with the laws of the Cayman Islands.

Yours faithfully
