EFFECTS OF VARYING THE MEDIA FOR BASE CLEAVAGE OF SOME BENZYL-SILICON AND-TIN COMPOUNDS IN ALCOHOLS
The effects on the rates of cleavage of 3-ClC6H4CH2MMe3 and 3,5-Cl2C6H3CH2MMe3 compounds with M = Si and Sn have been examined for (a) various concentrations of NaOMe-MeOH; (b) various concentrations of H2O in NaOH-H2O-MeOH; and (c) variation of R from Me to Et, i-Pr and t-Bu for metal alkoxide-ROH mixtures.Rates have also been measured for cleavages in NaOCH2CF3HOCH2CF3-Me2SO.In all cases there are differences in behaviour between the silicon and tin compounds which are consistent with the postulated difference in the mechanisms of their reactions.
