Abstract

A ligand component is formed according to formula (1):RP—X—N═C(R)—Y, wherein Ris Ph or Cyc or a C-Csubstituted or unsubstituted ailkyl group; each Ph is a substituted or unsubstituted phenyl group; each Cyc is a substituted or unsubstituted cycloalkyl group; X is an unsubstituted arylene or a C-Csubstituted or unsubstituted alkylene; Ris H, methyl or Ph; and Y N is pyridyl, 6-phenylpyridyl or 6-methylpyridyl; with the proviso that when X is a Csubstituted or unsubstituted alkylene and Y is pyridyl, Ris methyl or Ph. A reaction product including the ligand component and a metal precursor is prepared by combining the ligand component with the metal precursor. An activated reaction product is formed by activating the reaction product as a hydrosilylation catalyst.
