Catalytic silicon-carbon or silicon-heteroatom bond-forming hydrosilylation has become increasingly important in synthetic chemistry, catalysis and organosilicon chemistry. Herein we report a platinum-catalyzed one-pot and tandem hydrosilylation/cyclization of OH-containing alkynes with dihydrosilanes, allowing for facile synthesis of six-membered organosilicon compounds, including silyloxycycles and cyclic siloxanes in high yields and with good stereoselectivities.
