Diphenyl mercury dibromide

Evaporation of a solution of equimolar amounts of diphenyl tellurium dibromide and mercury(II) chloride in ethanol and extraction of the residue with hot chloroform gave diphenyl tellurium dichloride (m.p. 160°) in high yield. A similar reaction in chloroform converted dimethyl tellurium diiodide to the dichloride (m.p. 90°) in 95% yield3. 

Phenylmercuric bromide may be obtained from phenyl magnesium bromide and mercuric bromide in dry ether by the interaction of mercury diphenyl and two atoms of bromine if four atoms of the halogen are used, bromobenzene and mercuric bromide result, When mercury diphenyl and mercuric bromide in alcoholic solution are heated at 120° C., and when ethylene dibromide and mercury diphenyl are heated at 200° C. this bromide is also formed. 

Boron diphenyl bromide was first obtained as a by-product in the preparation of boron phenyl dibromide, from boron tribromide and mercury diphenyL the compound being contained in the fraction distilling above 150° C. at 20 mm. It may be more readily isolated by taking the proportions represented by the following equation —...
