摘要：
Disclosed are processes for the preparation of alkyl (alkoxycarbonylcyclohexyl)cyclohexenecarboxylates by the dimerization of alkyl 3-cyclohexenecarboxylates and the dehydrogenation of the alkyl (alkoxycarbonylcyclohexyl) cyclohexenecarboxylates to dialkyl biphenyldicarboxylates. The processes are especially useful for the preparation of dialkyl 4,4'-biphenyldicarboxylates which are intermediates in the preparation of high performance polyesters.
