Abstract

The generation of "MClL₂" centers in THF solution (M Ir, L AsPh₃, SbPh₃; M Rh, L SbPh₃) leads to stable η²-MCl(C₅H₈)L₂ complexes on the addition of an excess of trans-1,3-pentadiene. For IrCl(PPh₃)₂, it is only possible to recover a clean pentadiene complex if the reaction is carried out in neat diene solution. Cyclobutene also coordinates to "IrClL₂" (L AsPh₃, SbPh₃) to form an LrCl(C₄H₆)L₂ product when excess cyclobutene is condensed with a starting material at-78°C, THF is added, and the solution is warmed to 25°C. These 16-electron MCl(olefin)L₂ complexes are stable to disproportionation after isolation from solution. The most stable complexes are formed with the tertiary arsine and stibine ligands for M Ir.
