Metallation of 2-vinylpyridine by rhodium(III)
Abstract
Metallation of 2-vinylpyridine, (vpy), occurs on reaction with [Rh2X6(PBun3)4](X = Cl or Br) to give [[graphic omitted]HCH)py}X2(PBun3)2], which undergoes an unusual substitution reaction with bromine to give [[graphic omitted]HCBr)py}Br2(PBun3)2].
