DIMETHYLPHENYLSILANOL Usage And Synthesis

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.
