Abstract: A ligand component is formed according to formula (1):R12P—X—N?C(R2)—Y, wherein R1 is Ph or Cyc or a C1-C20 substituted 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 C2-C3 substituted or unsubstituted alkylene; R2 is H, methyl or Ph; and Y N is pyridyl, 6-phenylpyridyl or 6-methylpyridyl; with the proviso that when X is a C2 substituted or unsubstituted alkylene and Y is pyridyl, R2 is 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.
