Di-nitrogen ligands for supported coordinated platinum hydrosilylation catalysts

A supported platinum catalyst comprising:

• (i) a di-nitrogen ligand,
• (ii) a support comprising MgO, and
• (iii) an anchoring ligand,
• wherein the di-nitrogen ligand is of formula (I):
• wherein R1 and R2 are each, independently, a C3 to a C12 branched or unbranched alkyl group, a substituted or unsubstituted phenyl group, or a carboxylic acid group;
• wherein the anchoring ligand is 2,2′-bipyridine-4,4′-dicarboxylic acid or 1,10-phenanthroline-5,6-dione;
• wherein the di-nitrogen ligand in (i) and the anchoring ligand in (iii) complex with a platinum metal ion;
• and
• wherein the anchoring ligand in (iii) is deposited on the support in (ii).
