Abstract
The electron-rich alkene (R = CH2Ph) has been used as a source of various carbenerhodium(I) complexes: [RhC](cod)(L)] (1), [RhCl(L)3] (2), [RhCl(CO)(h)3] (3), and trans-[RhCl(CO)(L)2] (4), and of the iridium(I) complex [IrCl(L)3] (5). Compounds (2) and (5) are of particular interest as they contain no other neutral ligand apart from the carbene: (R = CH2Ph); their chemistry is in many ways related to that of the well known complexes [MCl(PPh3)3] (M = Rh or Ir). Thus, compound (2) readily loses a carbene ligand upon treatment with either carbon monoxide [ultimately to lead to (4)], or O2 to yield a compound tentatively formulated as [RhCl(L)2(O2)] (6). The x-ray structures of complexes (2) and (4) have been determined.
