A Cationic Unsaturated Platinum(II) Complex that Promotes the Tautomeration of Acetylene to Vinylidene
Complex [PtMe2 (PMe2 ArDipp2)] (1), which contains a tethered terphenyl phosphine (ArDipp2 =2,6-(2,6-(i) Pr2 C6 H3)2 C6 H3), reacts with [H(Et2 O)2 ]BArF (BArF(-) =B[3,5-(CF3 )2 C6 H3 ]4(-) ) to give the solvent (S) complex [PtMe(S)(PMe2 ArDipp2)](+) (2⋅S). Although...
An Unsaturated Four-Coordinate Dimethyl Dimolybdenum Complex with a Molybdenum-Molybdenum Quadruple Bond
We describe the synthesis, molecular, and electronic structure of the complex [Mo2Me2{μ-HC(NDipp)2}2] (2), that contains a dimetallic core with a Mo-Mo quadruple bond and features uncommon four-coordinate geometry and fourteen-electron count at each molybdenum atom...
Cationic Platinum(II) sigma-SiH Complexes in Carbon Dioxide Hydrosilation
The low electron count cationic platinum complex [Pt(ItBu’)(ItBu)][BArF], 1, interacts with primary and secondary silanes to form the corresponding σ-SiH complexes. According to DFT calculations the most stable coordination mode is the uncommon η1-SiH. The reaction of...
Methyl-, Ethenyl-, and Ethynyl-Bridged Cationic Digold Complexes Stabilized by Coordination to a Bulky Terphenylphosphine Ligand
Reactions of the gold(I) triflimide complex [Au(NTf2)(PMe2Arequation image)] (1) with the gold(I) hydrocarbyl species [AuR(PMe2Arequation image)] (2 a–2 c) enable the isolation of hydrocarbyl-bridged cationic digold complexes with the general composition...
