Description

Application

Triphenyltin hydride can be used as a reducing agent in:

• The reductive deselenenylation reaction in the presence of the catalytic amount of AIBN.
• The free radical hydrostannylations of olefins.
• The reduction of α, β-unsaturated ketones and esters.

It can also be used as a radical precursor in the free-radical reduction reactions in the presence of 9-borabicyclo[3.3.1]nonane (9-BBN) as an initiator.
