Thermal Oligosilane Synthesis via Successive Diphenylsilylene Transfer from (Aminosilyl)boronic Esters to Si–O and Si–H Bonds

Multiple insertions of diphenylsilylene into the Si–O and Si–H bonds of Me2PhSi–Y (Y = OMe or H) were achieved by a transition-metal-free diphenylsilylene (Ph2Si:) transfer from Ph2(Et2N)Si–B(pin). This reaction proceeded at 135 °C in toluene, yielding up to seven diphenylsilylene-linked silicon chains.
