Abstract

Reaction of Ph₂ SbCl₃ with 2,2'-bipyridine and Me₃ SiOSO₂ CF₃ releases chlorobenzene, which is interpreted as a reductive (Sb^V /Sb^III ) elimination from a complex of a stiboranium cation. Conversely, reactions of Ph₂ SbCl₃ with 4-methylpyridine-N-oxide and AgOSO₂ CF₃ give redox-resistant complexes with the generic formulae [Ph₂ SbCl_3-x L_x+1 ][OTf]_x , including a compound containing a pnictogen(V) trication.

Keywords: antimony; cations; redox reactions; trications.
