Transesterification
of ethyl-10-undecenoate (derived from castor
oil) with 1,4-cyclohexanedimethanol over a recyclable Cu-deposited
V2O5 catalyst afforded 1,ω-diene, the
corresponding cyclohexane-1,4-diylbis(methylene) bis(undec-10-enoate),
a promising monomer for the synthesis of biobased polyesters, in an
efficient manner. Deposition of Cu plays an important role in proceeding
the reaction with high selectivity, and both the activity and the
selectivity are preserved for five recycled runs by the addition of
the substrates. The present catalyst was effective for transesterification
with other alcohols, especially primary alcohols, demonstrating a
possibility of using this catalyst for efficient conversion of plant
oil to various fine chemicals.
