Synthesis of 1,1-disilanes
Recent Literature
The conversion of geminal dibromides into 1,1-disilylated alkanes in the
presence of a Si-B reagent as the silicon pronucleophile is promoted by a
copper(I) catalyst generated in situ from CuBr·SMe2 and 4,4′-di-tert-butyl-2,2′-bipyridine.
The two C(sp3)-Si bond-forming events differ in mechanism, with the
first being ionic and the second being radical.

An organocalcium complex catalyzes dehydrogenative silylation and mono/dihydrosilylation
tandem reactions of terminal alkynes with hydrosilanes to provide gem-disilylated
alkenes in moderate yields or gem-trisilylated alkanes in high yields.
The gem-disilylated alkenes can be easily transformed into other
organosilanes.
