Some sulfur-substituted organotin compounds, R3SnCH2X, where X = SCH3, SO2C4H9-n, SO2C6H5, S+(CH3)2Z−, etc., have been synthesized and studied with regard to their solvolytic and “organometallic-like” behavior. Reactions of the organotin compounds with substrates known to be reactive toward classical organometalliccompounds tend to place these materials by comparison on the lower end of the reactivity
