Direct metallation of cyclic conjugated hydrocarbons by highly reactive magnesium

Conclusions Organomagnesium compounds have been prepared by the direct metallation of cyclopentadiene, indene, fluorene, and cyclooctatetraene and by highly reactive magnesium. Their crosscombination with allyl and propargyl electrophiles in the presence of metal complex catalysts has been studied, this leading to the allyl and propargyl substituted hydrocarbons being obtained in high yields.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 2, pp. 428–431, February, 1988.
