Rates of cleavage (protodesilylation) of some trimethylsilyl derivatives of reduced benzocycloalkenes and o-xylene by a mixture of 10·6M-aqueous perchloric acid and methanol (2 : 5 v/v) have been measured spectrophotometrically. Values (min.–1) of the first-order rate constants (×103) at 50·0° are as follows: 3-trimethylsilyl-o-xylene, 193; 4-trimethysilyl-o-xylene, 153; 1,2-dihydro-3-trimethylsilylbenzocyclobutene
