Crossover Products from Joint Reactions of Alkenes, Alkynes, and Hydrogen Halides

Joint reactions of alkenes, alkynes, and hydrogen bromide or hydrogen chloride were examined.Ethylene was the only olefin which afforded a crossed cycloadduct, viz. 1-bromo-1-methylcyclobutane (3), in its reaction with propyne and HBr.Reactions of propene with propyne/HBr, with 1-butyne/HCl, and with 2-butyne/HCl as well as reactions of 1-butene with propyne/HBr gave only cyclic and/or acyclic crossover products, which are derived from alkylation of the alkyne by the alkene.Dihalotrialkylcyclobutanes were obtained as cyclic crossover products, which had carbon skeletons composed of two molecules of the acetylene and of one molecule of the olefin used.
