Abstract:
A process for preparing a variety of secondary and tertiary alkyl formate esters via the coupling of methanol and secondary (or tertiary) alcohols. Iron-based catalysts, supported by pincer ligands, are employed to produce these formate esters in high yields and unprecedentedly high selectivities (>99%). Remarkably, the coupling strategy is also applicable to bulkier tertiary alcohols, which afford corresponding tertiary formate esters in moderately high yields and high selectivities.

Claim (Index 2):
The process according to  claim 1 , wherein the catalyst is formed by introducing a pre-catalyst of the formulas (IIa) or (IIb): into the reactor and exposing the pre-catalyst to heat, an acid, a base, or combinations thereof; and wherein\n R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , E, and L are as defined in formula (I); \n Z is R 7  or X; \n R 7  is hydrogen or an alkyl or aryl group; \n X is [BH 4 ] \u2212  or a halide; and \n L 2  is a neutral ligand.
