Phenylation of Organic Derivatives of Mercury, Silicon, Tin, and Bismuth with Pentaphenylantimony and Pentaphenylphosphorus

Pentaphenylantimony and -phosphorus react with arylmercury chlorides in toluene at room temperature to give diaryl derivatives of mercury in yields of up to 95%. The reactions of pentaphenylantimony and -phosphorus with silicon and tin halides involve ary

Phenylation of Antimony(V) Organic Compounds with Pentaphenylantimony. The Structure of Tetraphenylantimony Chloride

Tetraphenylantimony chloride and bromide were synthesized through the reaction of pentaphenylantimony with diphenylantimony trichloride or tribromide taken at a molar ratio of 2:1 in toluene. When the initial compounds were taken at a molar ratio of 1:1, triphenylantimony dichloride or dibromide was formed. The phenylation of triphenylantimony sulfate with pentaphenylantimony yielded tetraphenylantimony sulfate. According to the X-ray diffraction data, the antimony atom in the tetraphenylantimony chloride molecule has a distorted trigonal bipyramidal configuration with the chlorine atom in the axial position. The Sb-Cl distance is equal to 2.686(1) and Sb-C distances are equal to 2.113(4) and 2.165(4) A (av. 2.130 A).
