Abstract

Treatment of trialkyl (dibromomethyl) silanes with trialkylmanganates, derived from manganese (II) chloride and three molar amounts of Grignard reagents or alkyllithiums, provided (E)-1-trialkylsilyl-1-alkenes with high stereoselectivity in good yields. The reaction of trialkyl (dibromomethyl) silanes with alkylmagnesium halides proceeded in the presence of a catalytic amount of manganese (II) chloride. Treatment of 1, 2-bis (dibromomethyl) ...
