Intermediacy of O-sulphinates in the reaction of transition-metal carbonyl alkyls and aryls with sulphur dioxide
Abstract
Spectroscopic (1H n.m.r. and i.r.), electrical conductivity, and chemical evidence indicates that reactions of π-C5H5Fe(CO)2R, π-C5H5Mo(CO)3R, and Mn(CO)5R (R = alkyl or aryl) with SO2 proceed via the intermediacy of the oxygen-bonded sulphinates, which subsequently rearrange to the thermodynamically stable and isolable sulphur-bonded sulphinates.
