Synthesis, Coordination Properties, and Catalytic Application of Triarylmethane-Monophosphines

A new class of triarylmethane-based phosphines (L1-L4) and their Pd(II) and Rh(I) complexes were synthesized and subsequently characterized by NMR spectroscopy and X-ray diffraction analysis. The reactions of these phosphines with [PdCl(π-allyl)]2 gave the square-planar Pd(II) complexes [PdCl(π-allyl)(L)] (L = L1-L4). The treatment of [PdCl(π-allyl)(L3)] and [PdCl(π-allyl)(L4)], which have CF3-substituted triarylmethane and 9-arylfluorene moieties, respectively, with LiOtBu afforded P,C(sp3)-chelated palladacycle complexes. Reversibility between a C(sp3)-M covalent bond and a C(sp3)-H···M interaction was experimentally demonstrated using [RhCl(nbd)]2 as a Rh(I) source. The triarylmethane-monophosphines L1-L4 were applied to the Pd-catalyzed 1,4-addition of arylboronic acids to enones.
