34867-87-3 Usage

General Description

Cyclobutane malonyl peroxide is a chemical compound that is primarily used as a radical initiator in various polymerization processes. It is a highly reactive compound, capable of undergoing rapid decomposition to form free radicals that initiate the polymerization of unsaturated monomers. Due to its stability and ability to generate radicals at lower temperatures, it is often used in the production of various polymer materials such as adhesives, coatings, and resins. However, it is important to handle this compound with caution as it is highly explosive and can pose significant safety risks if mishandled.

Check Digit Verification of cas no

The CAS Registry Mumber 34867-87-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,8,6 and 7 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 34867-87:
(7*3)+(6*4)+(5*8)+(4*6)+(3*7)+(2*8)+(1*7)=153
153 % 10 = 3
So 34867-87-3 is a valid CAS Registry Number.

Metal-free dihydroxylation of alkenes using cyclobutane malonoyl peroxide

Jones, Kevin M.,Tomkinson, Nicholas C. O.

experimental part, p. 921 - 928 (2012/02/16)

Cyclobutane malonoyl peroxide (7), prepared in a single step from the commercially available diacid 6, is an effective reagent for the dihydroxylation of alkenes. Reaction of a chloroform solution of 7 with an alkene in the presence of 1 equiv of water at 40 °C followed by alkaline hydrolysis leads to the corresponding diol (30-84%). With 1,2-disubstituted alkenes, the reaction proceeds with syn-selectivity (3:1 → 50:1). A mechanism consistent with experimental findings is proposed, which is supported by deuterium and oxygen labeling studies and explains the stereoselectivity observed. Alternative reaction pathways that are dependent on the structure of the starting alkene are also described leading to the synthesis of allylic alcohols and γ-lactones.
