Description

General description

Rhodium and triphenylphosphine catalyst system has been used for the hydroformylation of soybean, safflower and linseed oils and their methyl esters. Polymer supported triphenylphosphine has been reported to efficiently catalyze the γ-addition of pronucleophiles to alkynoate. Triphenylphosphine reacts with hydrated ruthenium trichloride in methanol to afford [RuCl₂(PPh₃)₄], [RuCl₂(PPh₃)₃] and [RuCl₃(PPh₃)₂CH₃OH]. It participates in the Heck reaction of 4-bromoanisole and ethyl acrylate in ionic liquids.

Application

Triphenylphosphine was used in the synthesis of mono-6-amino-deoxy-6-cyclodextrin. It was also employed as catalyst during the synthesis of C-aryl furanosides.
