250 mg of the oils shown in Table 2, were taken in 1ml hexane respectively and passed on silica gel column (60-120 mesh) and eluted with Petroleum ether, diethyl
ether and acetic acid (70:30:1) mixture.
Here we report the results for the reactions of tetraethoxysilane with n-butylmagnesium chloride solvated with dibutyl ether, diethyl
ether, and THF, and with isopropylmagnesium chloride in the presence of diethyl ether, and also for the reaction of isopropyltriethoxysilane with n-butylmagnesium chloride solvated with diethyl ether.
In a scale of increasing polarity, they were: petroleum ether, diethyl
ether, ethanol, and water.
