Organoantimony p-Nitrosophenol Derivatives

摘要

Two organoantimony nitrosophenol derivatives Ph_4SbONC_6H_4O and p-Tol_4SbONC_6H_4O were synthesized by the reactoin of pentaarylantimony Ar_5Sb (Ar = Ph, p-Tol) with p-nitrosophenol in benzene at 20 deg C. The Sb atom in the molecule of the crystal solvate Ph_4SbONC_6H_4O·0.5C_6H_6 has trigonal-bipyramidal coordination with an axial iminoquinone ligand; associate formation does not occur.
