Abstract: | Primary alkylmagnesium bromides are prepared in hydrocarbon solutions such as benzene or toluene using 1 equivalent of diethyl ether or tetrahydrofuran. Their reactions with diisopropylketone and cyclohexylisopropylketone increase drastically the addition products in comparison with the reactions in diethyl ether or in tetrahydrofuran. No important differences were found in the distribution of reaction products between diethylether or tetrahydrofuran and between benzene and toluene when they are used as complexant and diluent respectively. |
