Abstract The rates of cleavage of the aryl-Si bonds in (Me 3 Si) x CH 3-x C 6 H 4 SiMe 3 compounds by aqueous methanolic perchloric acid, and thus the electron release by the (Me 3 Si) x CH 3-x groups, increase in the order x= 0< 3< 1< 2 for both the m-and p- compounds. The 19 F chemical shifts in the p-(Me 3 Si) 3 CH 3-x C 6 H 4 F compounds indicate the same order of electron release. This order is not consistent with attribution of ...
