✦ Synopsis

Abstract

The NMR spectroscopy data for five hydroformylation catalysts RhH(CO)~2~(P‐P) (P‐P = diphosphite bidentate ligand) are reported and interpreted in terms of equatorial and axial coordination of the phosphorus and carbon monoxide ligands in a trigonal bipyramidal structure.

## Abstract Here, we describe the successful application of novel glucofuranose‐derived 1,3‐diphosphites in the rhodium‐catalysed asymmetric hydroformylation of vinyl acetate, 2,5‐dihydrofuran and 2,3‐dihydrofuran. In the hydroformylation of vinyl acetate, total regioselectivity and high __ee__ (up
