isomeric tetradecynoic acids were isomerized with the sodium salt of 1,2-diaminoethane. Isomers having the triple bond near the carboxyl group rearranged to E,Z-3,5- and E,E-3,5-tetradecadienoic acids (1 and 2), the former compound being the sex pheromone of the blackcarpetbeetle. Isomers having the triple bond closer to the terminus of the chain afforded some 13-tetradecynoic acid along with 1 and 2
Cyclopropene derivatives of high purity were prepared by reaction of acetylenes with a rhodium carbenoid bound to a polystyrene resin. This solid phase method avoids the formation of undesired byproducts obtained in the corresponding solution reaction and an eventual extension to combinatorial synthesis of cyclopropene derivatives could be achieved.
