AbstractThe scandium complex bearing both methylidene and phosphinidene ligands, [(LSc)2(mu(2)-CH2)(mu(2)-PDIPP)] (L = [MeC(NDIPP)CHC(NDIPP)Me](-), DIPP = 2,6-(Pr-i)(2)C6H3) (2), has been synthesized, and its reactivity has been investigated. Reaction of scandium methyl phosphide [LSc(Me){P(H)DIPP}] with 1 equiv of scandium dimethyl complex [LScMe2] in toluene at 60 degrees C provided complex 2 in good yield, and the structure of complex 2 was determined by single-crystal X-ray diffraction. Complex 2 easily undergoes nucleophilic addition reactions with CO2, CS2, benzonitrile, and tert-butyl isocyanide. In the above reactions, the unsaturated substrates insert into the Sc-C(methylidene) bond to give some interesting dianionic ligands while the Sc-P(phosphinidene) bond remains untouched. The bonding situation of complex 2 was analyzed using DFT methods, indicating a more covalent bond between the scandium ion and the phosphinidene ligand than between the scandium ion and the methylidene ligand.
