Abstract
Alkyl silanes are prepared by silylating an unsaturated hydrocarbon with an Si—H functional silane employing an iridium chloride coordination compound as a catalyst and a polymeric polyene as a cocatalyst. Reaction bottoms can be worked up to provide an iridium-containing composition which remains catalytically active.
