Abstract
New esters are provided by reaction of an ester of the formula: <IMAGE> (IV) in the presence of a compound of rhodium and an alcohol with a 1,3-butadiene of the formula: <IMAGE> (V) in which R1 represents an alkyl radical having from about 1 to 6 carbons atoms, R2, R3, R5, R8 and R9, which are identical or different, are a hydrogen atom or an alkyl radical having from about 1 to 3 carbon atoms. R4, R6, and R7 represent a hydrogen atom or an alkyl radical having from about 1 to 3 carbon atoms, at least one of them being a hydrogen atom, R10, R11, R12, and R13 represent a hydrogen atom or an alkyl radical having from about 1 to 3 carbon atoms, at least one of them being a hydrogen atom, R14, R15, R16, and R17, which are identical or different, each represents a hydrogen atom or an alkyl radical. These new esters can be used as intermediates for the preparation of alcohols after hydrogenation and hydrogenolysis and for the preparation of soaps after hydrogenation and saponification.
