Pentaphenylantimony and pentaphenylbismuth as phenylation agents in the reactions with organic compounds of elements (review)

The results for the phenylation of organoelement derivatives by pentaphenylantimony and pentaphenylbismuth are represented. Much attention is paid to the ligand redistribution reactions involving the derivatives of antimony(V) and bismuth(V) of the general formula Ph 3EX 2 (E = Sb, Bi; X - electronegative ligand). The influence of reaction conditions on the structure and yield of the desired product.
