Metalloradical-catalyzed rearrangement of cycloheptatrienyl to benzyl

摘要

Rh(ttp)(C_7H_7) rearranged to give Rh(ttp)(CH_2Ph) quantitatively at 120℃ in 12 d (ttp = 5,10,15,20-tetratolylporphyrinato dianion). This process is 10~(10) faster than for the organic analogue. Mechanistic investigation suggests that a Rh~Ⅱ(ttp)-catalyzed pathway is operating.
