A new chiral trisphosphite ligand, (S,S,S)-2,2',2-tris(2,4,8,10-tetra- tert-butyl-dibenzo[d,f][1,3,2]dioxaphosphepin-6-yl-6-oxy)tri-2-propylamine, (S,S,S)-TRISPHOS, was synthesized and coordination chemistry investigated. The Rh(I)-(S,S,S)-TRISPHOS complexes were found to be effective catalysts for the enantioselective hydrosilylation of ketones.
Facile phosphite to phosphonate rearrangement of a trialkanolamine-derived triphosphite promoted by triethylaluminum

A facile room temperature rearrangement of a trialkanolamine-derived triphosphite, 1, to the monophosphonate 5 promoted by three equivalents of triethylaluminum is described. The diphosphonate 6 was prepared by the addition of three equivalents of triethylaluminum to the monophosphonate 5. A mechanism is suggested involving a transition state or intermediate with coordination of the trialkylaluminum to the migrating oxygen. Copyright Taylor & Francis Group, LLC.
