N2 - 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.
