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 3):
The process according to  claim 1 , wherein the catalyst is formed by:\n (a) introducing (i) an iron salt or an iron complex comprising the neutral ligand (L), (ii) a ligand of the formula (III): and (iii) optionally the neutral ligand (L) into the reactor to form a pre-catalyst mixture; and\n (b) optionally exposing the pre-catalyst mixture to heat, an acid, a base, or combinations thereof; \n wherein R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , and E are as defined in formula (I).
