Uses
Methyl 1-cyclopentene-1-carboxylate may be used as starting material in the synthesis of pinnaic acid and halichlorine. It undergoes asymmetric oxidative Heck reaction with aryl boronic acids to form coupling products in the presence of chiral NHC (N-heterocyclic carbine)-palladium (II) complex.
General Description
Methyl 1-cyclopentene-1-carboxylate, a cyclic alkene, is a cyclopentene derivative. It participates in the synthesis of azulene derivatives by initially forming the corresponding cyclopropanol followed by oxy-Cope rearrangement.
Check Digit Verification of cas no
The CAS Registry Mumber 25662-28-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,6,6 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 25662-28:
(7*2)+(6*5)+(5*6)+(4*6)+(3*2)+(2*2)+(1*8)=116
116 % 10 = 6
So 25662-28-6 is a valid CAS Registry Number.

Oxidative carbomethoxylation of alkenes using a Pd(II)/molybdovanadophosphate (NPMoV) system under carbon monoxide and air

Oxidative carbomethoxylation of cyclopentene (1) under carbon monoxide and air by the use of a catalytic amount of Pd(OAc)2 and molybdovanadophosphate (NPMoV) led to dimethyl cis-1,2-cyclopentanedicarboxylate (2) and dimethyl cis-1,3-cyclopentanedicarboxylate (3) in good yields. Total yields of 2 and 3 were found to be improved by adding a small amount of NH4Cl. Several alkenes were similarly converted into the corresponding dimethyl dicarboxylates. The role of Cl- in the present catalytic system is suggested.
