DIMETHYLPHENYLSILANOL Chemical Properties,Uses,Production

Chemical Properties

DIMETHYLPHENYLSILANOL is Colorless or yellowish transparent liquid

Uses

DIMETHYLPHENYLSILANOL is a useful silicon nucleophile for Pd-catalyzed cross-coupling.1

Uses

Dimethylphenylsilanol is an organosilanol that can be used:

As a coupling partner in the Pd(II) catalyzed Hiyama reaction for C5 C-H bond functionalization of 2,3-dihydropyridin-4(1H)-ones.
To introduce dimethylphenylsilyl end group on highly branched poly(dimethylsiloxane) polymers.
As a substrate in the Ru(0) catalyzed germasiloxanes synthesis by reacting with vinylgermanes.
