Catalytic cyclometallation of styrene, m-methylstyrene, p-tert-butylstyrene, and 1-hexene with di n-alkylmagnesium compounds (n-R2Mg, where R=C3H7, C4H9, C6H13) in the presence of Cp2Zr2Cl2 has been given high yields of 2,4-disubstituted magnesiocyclopentanes.The probable mode of formation of magnesiocyclopentanes, involving zirconocyclopentanes formed from Cp2ZrCl2, n-R2Mg, and the appropiate olefins as reactive intermediates in the cyclometallation, is discussed. Keywords: catalytic synthesis, substituted styrenes, alkenes, magnesium alkyls.
