A composition contains (A) a hydrosilylation reaction catalyst and (B) an aliphatically unsaturated compound having an average, per molecule, of one or more aliphatically unsaturated organic groups capable of undergoing hydrosilylation reaction. The composition capable of reacting via hydrosilylation reaction to form a reaction product, such as a silane, a gum, a gel, a rubber, or a resin. Ingredient (A) contains a metal-ligand complex that can be prepared by a method including reacting a metal precursor and a ligand. |

1. A method comprising:(1) combining ingredients comprising a Cu precursor and a ligand, thereby preparing a reaction product, where
the Cu precursor has formula (i) Cu-A, where each A is independently a displaceable substituent; and the ligand is one of ligands (a) and (b), whereLigand (a) is a compound of general formula (ii)where each Q1 and each Q2 is independently a group of formula (CM2)a where each subscript a is independently an integer from 1 to 5, and each M is independently selected from H, a halogen atom, and a monovalent organic group;
A1, A2, A3, A4, A5, A6, and A7 are each independently selected from H, a halogen atom, and a monovalent organic group, with the provisos that A1 and A2 may bond together to form a ring structure and/or A3 and A4 may bond together to form a ring structure, and A5 and A6 may bond together to form a ring structure, and/or A6 and A7 may bond together to form a ring structure; orLigand (b) is |
