Title:
LIGAND COMPONENTS, ASSOCIATED REACTION PRODUCTS, ACTIVATED REACTION PRODUCTS, HYDROSILYLATION CATALYSTS AND HYDROSILYLATION CURABLE COMPOSITIONS INCLUDING THE LIGAND COMPONENTS, AND ASSOCIATED METHODS FOR PREPARING SAME
Document Type and Number:
WIPO Patent Application WO/2016/099727
Kind Code:
A3
Abstract:
A ligand component is formed according to formula (1 ):R 1 2P-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 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.
