A combination of zinc triflate and pyridine in a nitrile medium was found to act as an effective catalytic system for dehydrogenativesilylation with flexible pieces of terminalalkynes and hydrosilanes, thereby producing diverse alkynylsilanes in high to excellent yields.
A phosphine-assisted platinum-catalyzed mono-lateral diboration of dialkynylsilanes for the construction of silicon-tethered alkynyl diborylalkenes with or without silicon-stereogenic centers is described.
