Application

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.
