Phenylmercury chloride

Pd(II) salts promote the carbonylation of organomercury compounds. Reaction of phenylmercury chloride and PdCh under CO pressure affords benzophenone (429)[387]. Both esters and ketones are obtained by the carbonylation of furylmercury(Il) chloride in alcohol[388]. Although the yields are not satisfactory, esters are obtained by the carbonylation of aryl- and alkylmercuryfll) chlorides[389,390]. One-pot catalytic carbonylation of thiophene, furan, and pyrrole (430) takes place at the 2-position via mercuration and transmetallation by the use of PdCb, Hg(N03), and CuCl2[391].

Pyrazoles were chloromercurated at C-4 giving (316) by reaction with mercury(II) chloride (B-76MI40402, 66AHC(6)347). The mercury group in (316) behaves in a variety of reactions just as phenylmercury chloride. 1-Phenylpyrazole reacts with mercury(II) acetate to yield the 4-acetoxymercury derivative (317). The same reactions with 3 (5)-phenylpyrazole also introduce the acetoxymercury group at position 4 and not on the nitrogen atom.

This method permits vinylation of aromatic compounds. In the isoflavanone synthesis, 4-chromanone (44) is converted to the enol ester 45, which is reacted with phenylpalladium acetate, formed in situ from phenylmercury chloride and Pd(OAc)2, to give — after hydrolysis - isoflavanone (46) (Schema 15). A simple synthesis of... 

Phenylmercury chloride (CjHjHgCl) can be precipitated from the aqueous solution of phenylmercury acetate by the addition of sodium chloride. The active substance can be also prepared directly from aniline by Nesmejanov synthesis. Being only slightly soluble in water, it is less phytotoxic than the acetate. It is used... 

Russel [142] developed a method based on the conversion of chlorine, bromine and iodine ions into the corresponding halogenated ethanols by reaction with ethylene oxide. Belcher et al. [143] offer a method for determining trace amounts of chloride ions, based on reaction with mercury phenylnitrate to give phenylmercury chloride, which is chromatographed with flame-ionization detection.

Treatment of phenylmercury chloride with arsenic trichloride has been suggested as an industrial method for preparing chlorodiphenylarsine 112). However, Mann and Watson found that the mercurial method was not good for the preparation of aromatic arsenicals of the type ArAr AsCl by the reaction...
