The Reaction of [Cp*RhCl2]2, Aniline, and a Terminal Alkyne: Formation of Cyclometalated Rhodium(III) Complexes
摘要:
The reaction of [Cp*RhCl2](2) with an aniline (R'NH2) and a terminal alkyne (RCCH) afforded the N-containing cyclometalated rhodium complexes Cp*Rh(Cl)[N(R')=C(CH2R)-CH=CR] via a hydroamination and a 1,2-insertion of an alkyne. A reaction pathway has been proposed on the basis of deuterium labeling experiments and computational studies.
