摘要：

The collision induced loss of ethene from deprotonated ethyl methyl sulfoxide yields the methylsulfinyl anion (CH3SO-) as the major ionic product. This species is a weak base (DELTAG-degrees(acid) (CH3SOH) = 352 +/- 3 kcal mol-1) and a weak oxidising agent. For example it reacts with CS2 and SO2 in slow reactions to form OCS2.- and SO3.- respectively. The major ionic product of the reaction between CH3SO- and CS2 is the methyl disulfide ion CH3SS-. This species is quite unreactive, consonant with its low basicity (DELTAG-degrees(acid) (CH3SSH = 345 +/- 3 kcal mol-1). It reacts with SO2 by (i) a fast electron transfer reaction to form SO2.- and (ii) a slow S/O exchange to form CH3SO-.
