1,3-Dimethylenecyclobutane and 1-methyl-3-methylenecyclobutene are metallated in the presence of THF by alkyllithium compounds under mild conditions with the formation of one and the same organolithium compound of the π-pentadienyl type. Under the s

1. From their1H and13C NMR spectra, polymers of 1,2-dimethylenecyclobutane obtained by radical polymerization contain 85–90% of units containing the cyclobutene and 10–15% of units with the methylenecyclobutane structure. 2. The presence in the p

1. The possibility of polymerizing 1,2-dimethylenecyclobutane with organolithium initiators has been demonstrated. The microstructure of the polymers obtained is determined by the nature of the solvent; in a hydrocarbon medium the 1,4-structural unit
