TRI-N-BUTYLGERMANE Chemical Properties,Usage,Production

Chemical Properties

clear colorless liquid

Chemical Properties

Reduces acid chlorides to aldehydes in presence of Pd(0). Effects free-radical reductive addition of alkyl halides to olefins. Reduces benzylic chlorides 70x faster than silyl hydrides.

Uses

Efficient reducing agent for benzylic chlorides.1

Uses

Tri-n-butylgermanium hydride is used in the reduction of benzylic chlorides. It is also used as pharmaceutical intermediate.

General Description

Tributylgermanium hydride is a radical generating reagent. Reductive alkylation of active olefins with alkyl halides with tributylgermanium hydride was investigated in detail.
