Abstract
Carbomagnesiation of 1-alkenes with EtMgX (X = Cl, Et) has been implemented in the presence of TaCl5 as a catalyst to give a mixture of 2-(R-substituted)- and 3-(R-substituted)-n-butylmagnesiums (5:4 ratio) ina total yield of 98%. The probable mechanism of their formation through tantalacyclopentanes as key intermediates is discussed.
