ABSTRACT:
A method is disclosed for the production of esters by reaction of an alkyl acyclic allylic ether such as 8-methoxy-1,6-octadiene with carbon monoxide in the presence of a halide of nickel, cobalt or iron as a catalyst and especially nickel iodide for the production of esters. Carbonylation of 8-methoxy-1,6-octadiene results in the production of methyl-3,8-nonadienoate; 2-(carbomethoxymethyl)-vinylcyclopentane; 2-(carbomethoxymethyl)-6-vinylcyclohexanone and 2-carbomethoxymethylbicyclo(3.3.0)-octan-3-one.
