ABSTRACT:
An improved process for hydrosilating alkynes with hydridosilane using a cycloalkadiene-platinum complex as catalyst. The use of the cycloalkadiene-platinum complex as catalyst in the process reduces formation of the bis-silated adduct of the alkynes, when compared to the use of standard platinum-based hydrosilation catalysts.
