acidities of 15 simple alkanes have been determined in a flowing afterglow-selected ion flow tube (FA-SIFT) by a kinetic method in which alkyltrimethylsilanes were allowed to react with hydroxide ions to produce a mixture of trimethylsiloxide ions by loss of alkane and alkyldimethylsiloxide ions by loss of methane. The reaction is proposed to proceed by addition of hydroxide ion to the silane to form

Phenyl(bromodichloromethyl)mercury-derived dichlorocarbene inserts into the β CH bonds of Me3MCH(CH3)CH2CH3 and Me3MCD(CH3)CH2CH3 (M = Si and Sn) to give Me3MCH(CH3)CH(CH3)CCl2H and Me3MCD(CH3)CH(CH3)CCl2H, respectively. That no rearrangement of deuterium to the β position occured was suggested by the 13C and 1H NMR spectra of the products. This result is taken to speak against the intervention of
