Metalloradical-catalyzed rearrangement of cycloheptatrienyl to benzyl†
Abstract
Rh(ttp)(C7H7) rearranged to give Rh(ttp)(CH2Ph) quantitatively at 120 °C in 12 d (ttp = 5,10,15,20-tetratolylporphyrinato dianion). This process is 1010 faster than for the organic analogue. Mechanistic investigation suggests that a RhII(ttp)-catalyzed pathway is operating.
