Bis(diphenylphosphino)methane-1-indenylide, 1-C9H6PPh2CH2PPh2 (1-C9H6dppm, I), has been synthesized and characterized by NMR spectroscopy and X-ray crystallography.

Abstract
Bis(diphenylphosphino)methane-1-indenylide, 1-C9H6PPh2CH2PPh2 (1-C9H6dppm, I), has been synthesized and characterized by NMR spectroscopy and X-ray crystallography. I reacts with [CpRu-(MeCN)3]PF6 to form the conventional sandwich complex [CpRu(η5-I)]PF6 (II), which contains a dangling −PPh2 group. Complex II isomerizes to the 18-electron species IIIc, in which the dangling −PPh2 group coordinates to the ruthenium, forcing slippage of the five-membered ring to an unanticipated 1,9,8-η3-exo mode of coordination.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
