Stannyl anions organotins

Another application of the direct alkylation of metal-14 anions is the synthesis of polymer-supported organotin hydrides. These were prepared by the reaction of stannyl group was separated from the phenyl ring of polystyrene by two, three or even four carbon spacers. These polymers were found to contain 0.8-1.4 mmol of Sn-H per gram. The reducing ability of the polymer-supported organotin hydrides was monitored by reactions with haloalkanes (Scheme 22)142. 

Photoassisted electron transfer can be induced between a triaryltin chloride and an electron-rich olefin to give the organotin radical anion and then the neutral stannyl radical (equation 20-17).46...
