Strongly electron withdrawing cyanoolefins tetracyanoethylene (tcne) and 7,7,8,8‐tetracyano‐ p ‐quinodimethane (tcnq) react with [( η 5 ‐C 5 Me 5 )MCl(MDMPP‐ P , O )] (M=Rh, Ir; MDMPP‐ P , O =PPh 2 (2‐O‐6‐MeO‐C 6 H 3 ), a P,O chelating phosphane) by insertion into the C−H bond adjacent to the M−O σ bond. The crystal structure of the iridium complex formed upon insertion of tcne is shown.
