  名称：

  C–H Activation of 3,3-diphenylcyclopropene in the reaction with Os(CO)2(PPh3)3: 3,3-diphenylcyclopropenyl, 2,2-diphenylcyclopropyl, and 3-phenylindenyl complexes of osmium(II)

  摘要：

  Reaction between Os(CO)(2)(PPh3)(3) and 3,3-diphenylcyclopropene under quartz-halogen irradiation leads to C(sp(2))-H bond activation and the formation of the 3,3-diphenylcyclopropenyl complex, OsH[C3H(Ph-2)(2)](CO)(2)(PPh3)(2) (1). When complex 1 is heated there is ring-opening of the cyclopropene ring and rearrangement to the 3-phenylindenyl complex, OsH[C9H6(Ph-3)](CO)(2)(PPh3)(2) (2). Compound 1 reacts with HCl forming the 2,2-diphenylcyclopropyl complex, OSCl[C3H3(Ph-2)(2)](CO)(2)(PPh3)(2) (3). Reaction of either 1 or 3 with excess HCl leads to reversible formation of the hydroxycarbene complex, OSCl2[=C(OH)C3H3(Ph-(2))(2)](CO)(PPh3)(2) (4), through protonation of the acyl group formed by a migratory insertion reaction involving a carbonyl ligand and the sigma-bound 2,2-diphenylcyclopropanyl ligand. An X-ray crystal structure determination of 2 is reported. (c) 2006 Elsevier B.V. All rights reserved.
