Organotin compounds, hydrogen bond

It is difficult to reduce the vinyl group without also cleaving the C-Sn bond. The normal hydrogenation catalysts are apparently poisoned by organotin compounds, but this reduction has been achieved with a rhodium catalyst (equation 8-35),69 and P-stannyl-acrylates can be reduced to P-stannylpropionates with triethylsilane in the presence of... 

Fewer organoantimony compounds containing hydrogen-bonds leading to supra-molecular self-organization have been described. It can be expected that many analogies with organotin compounds are possible and perhaps this will stimulate a search for such structures. 

The increase in activity in the field of organotin hydrides is mostly due to the facility of addition of the tin-hydrogen bond to unsaturated systems and to the multiple mechanistic investigations of the hydrostannation reaction. Hev is a number of organometallic reactions, i.e., addition to transition metal complexes7 condensation with metal alkyls yielding tin-metal derivatives and with metal amides for synthesis of compounds with longer tin chains.
