Phosphine induced cyclopentadienyl ring slippage catalyzes CO insertion into a methyl rhenium compound to produce an acetyl rhenium compound


Journal Article

The carbonylation of (η5-C5H5)Re(NO)(PMe3)(CH3) (1) to form (η5-C5H5)Re(NO)-(PMe3)(COCH3) (4) under 4.95 atm CO at 90°C is accelerated by a factor of > 25 in the presence of 0.28 M PMe3. Kinetic studies established a third order rate law: Rate = k3 [1] [PMe3][p(CO)] where k3 = (7.52±0.36) × 10-5 M-1 atm-1 s-1 at 90°C. Kinetic and phosphine exchange studies are in agreement with a mechanism initiated by phosphine induced ring slippage. © 1992.
