Abstract

We have developed a new class of electron-deficient aminophosphonite–phosphite ligands based on (1 R ,2 S )-ephedrine and chlorophosphites. These ligands were tested in rhodium catalysed hydroformylation of styrene and led to reactions with high regio and chemoselectivities into the branched aldehyde but nevertheless with low enantioselectivities.

Abstract

Sucrose-butadiene telomerization is efficiently carried out in water or water-organic medium in the presence of a palladium salt and TPPTS (TPPTS = trisodium tris(m-sulfonatophenyl)phosphine as catalyst. Mono- and dioctadienylether compounds are selectively obtained using a NaOH 1 M/isopropanol mixture.

Abstract

New polyenes are formed in protic media via nickel catalyzed cooligomerization of butadiene with methyl acrylate. High activities are achieved with amino-phosphinite ligands in aprotic solvent. Using a deuterium labeled ligand, the presence of the NH group of the ligand is shown to be the key point for the proton transfer involved in the mechanism.
