Claim Text:
1. A method of making a transition metal bis(phenolate) compound having the formula: the method comprising: (i) contacting a phenol compound having the formula:  with in the presence of a reaction solvent to form a first mixture; (ii) contacting the first mixture with a palladium cross-coupling catalyst system and a substituted or unsubstituted, saturated or unsaturated, C to form a ligand reaction mixture comprising a bis(phenol) ligand compound having formula (II):  and (iii) contacting the ligand compound having formula (II) with M(X)(X)(X)(X), optionally in the presence of a second solvent, to form a transition metal compound reaction mixture comprising the transition metal bis(phenol) compound having formula (I); wherein: R  is a substituted or unsubstituted, saturated or unsaturated, C each X M is Ti, Zr, or Hf; each X independently is a monoanionic ligand; and each L independently is a neutral ligand, wherein n is 0, 1 or 2.
