Abstract

Whereas the reaction of the anionic palladium metallacycle [K{P [upper bond 1 start] d(CH₂CMe₂-o-C [upper bond 1 end] ₆H₄)(κ²-Tp)}] with CH₂Cl₂ leads to the isolation of the stable Pd(IV) chloromethyl complex [Pd(CH₂CMe₂-o-C₆H₄)(κ³-Tp)(CH₂Cl)], the analogous reactions with CH₂Br₂ and CH₂I₂ give rise to the six membered metallacycles [P [upper bond 1 start] d(CH₂CMe₂-o-C₆H₄(C [upper bond 1 end] H₂))(κ³-Tp)X] (X = Br or I), as a result of the formal insertion of CH₂ into the Pd–C_aryl bond.
