An unusual autocatalysis with an air-stable Pd complex to promote enantioselective synthesis of Si-stereogenic enynes

A highly enantioselective palladium-catalyzed hydrosilylation of 1,3-diynes with dihydrosilanes was established for the facile preparation of Si-stereogenic enynes and an enyne-linked chiral polymer (polyenyne) in good yields with excellent ees.
