In conjunction with a research program on Diels-Alder polymers, we recently reported the synthesis of 2-~ inyl-l, 3-butadiene,~ which is the simplest bifunctional diene. In order to produce a series of bifunctional dienes, we became interested in dienes with functional groups substituted in the 2-or 3-position. Although there are many dienes containing alkyl groups in the 2-position, very few compounds are known with functional groups in this ...
