Beschreibung

Anwendung

Triphenyltin hydride can be used as a reducing agent in:

• The reductive deselenenylation reaction in the presence of the catalytic amount of AIBN.[1]
• The free radical hydrostannylations of olefins.[2]
• The reduction of α, β-unsaturated ketones and esters.[3]

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.[4]
