Approaches to water-soluble phosphines are described which involve conversion of ethylene glycol derivatives and sugar diacetonides into monoallylethers, and hydrophosphorylation of the latter. In the case of the sugars, water-solubility is conferred by a subsequent hydrolysis.
TRANSITION METAL PHOSPHINE COMPLEXES POSSESSING A PHASE TRANSFER FUNCTION. PREPARATION AND PROPERTIES OF POLYETHER-SUBSTITUTED PHOSPHINES AND THEIR PALLADIUM COMPLEXES
For the purpose of endowing transitionmetal phosphine complexes with a phase transfer function, tertiary phosphines modified by polyether chains were prepared, and their properties were examined. The palladium complexes of these phosphines were very efficient as catalysts for the reduction of bromobenzene with sodium hydride under a liquid–solid two-phase condition.
