Rates of cleavage have been measured spectrophotometrically for some PhS–MR3 compounds (M = Si, Ge, Sn, and Pb) in neutral and acidic aqueous dioxan. The reactivity sequences are unrelated to the electronegativity of the metals and the ease of clea

Rates of reduction by sodium borohydride in propan-2-ol have been measured for the 2-furyl and 2-thienyl ketones 2-(XC6H4CO)C4H2YE (E = O or S) for a range of X groups with Y = H, and of Y groups with X = H. The results permit direct comparisons to b

Trimethylphenylthiosilane has been shown to catalyse the addition of benzenethiol to isocyanates, isothiocyanates, activated double and triple bond, and ketens. This silicon catalyst appears much more effective than the tin and lead counterparts, for
