Disclosed herein is the use of manganese, iron, cobalt, or nickel complexes containing tridentate pyridine di-imine ligands as hydrosilylation catalysts. These complexes are effective for efficiently catalyzing hydrosilylation reactions, as well as offering improved selectivity and yield over existing catalyst systems.

Non-precious metal-based hyrdosilylation catalysts exhibiting improved selectivity

A water soluble silicone macromer comprising a siloxane backbone having grafted thereto a suitable number of hydrophilic groups to render the macromer water soluble, the macromer comprising a polymerizable functional group grafted to the siloxane backbone. In one aspect, the present invention provides a water soluble silicone macromer having a structure of Formula (1): where M is a hydrophilic group or segment; L is a hydrophilic or hydrophobic linkage; N is a hydrophilic or hydrophobic group or segment. Q is a polymerizable functional group; x is zero or an integer greater than zero; y is zero or an integer greater than zero; v is zero or an integer greater than zero; and z is greater than zero, with the proviso that both y and v are not zero.
