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.

Hydroalkoxylation of C–C double bonds was achieved through the use of a rutheniumcatalyst. The reaction of allylic alcohols with nucleophilic alcohols was carried out in the presence of a rutheniumcatalyst prepared by RuClH(CO)(PPh3)3 and 2,6-bis(n-butyliminomethyl)-4-(piperidin-1-yl)pyridine under mild reaction conditions to afford the corresponding γ-alkoxypropanols in good yield.
