Title:
PYROPHOSPHORIC ACID ESTER COMPOUND, BISPHOSPHORIC ACID ESTER COMPOUND, AND CATALYST
Document Type and Number:
WIPO Patent Application WO/2014/014035
Kind Code:
A1
Abstract:
The invention pertains to a novel pyrophosphoric acid ester compound represented by formula (1) and a bisphosphoric acid ester compound represented by formula (2). In the formulas, R is an aryl group, organic silyl group, or halogen atom. These compounds can adequately activate carbonyl compounds, imine compounds, and the like due to having higher acidity than conventional phosphoric acid ester compounds. Usefulness as a metal ligand is also expected.
