Abstract

This paper reports the synthesis of polyene oligomers (“oligoenes”) that contain up to 15 double bonds that are identical to the “all five-membered ring” species formed through cyclopolymerization of diisopropyldipropargylmalonate. The oligoenes contain an isopropylidene unit at each end. The isolated oligoenes range from the “dimer”(a pentaene,(E)-di-1, 2-[1-(2-methyl-propenyl)-4, 4-di-iso-propyl-carboxy-cyclopent-1-enyl]- ...
