Synthesis of reactive organotin dichlqrides from organomercury compounds and SnCl2 in dimethoxyethane

Abstract: Some organotin dichlorides of general formula R2SnCl2, where R = p-anisyl, p-N,N-dimethylamino-phenyl, p-N,N-diethylaminophenyl orα-thienyl, were synthesized by heating the apropriate symmetrical mercury compounds with anhydrous SnCl2 in dimethoxyethane.

Synthesis of organomercury compounds from hydrazones Communication 1. Reaction of hydrazones of aliphatic aldehydes and ketones with mercuric acetate

Abstract: 1. The reaction of acetaldehyde, acetone, methylethyl ketone and butyrone hydrazones with mercuric acetate p rovides a method of preparation of some new types of organomercury compounds. 2. This reaction is of the “conjugated addition” type with the medium taking part. In water, α,α′-dimercurated or α,α′,ββ′-tetramercurated ethers are formed, in methanol-α-mercurated or α,β-dimercurated alkylmethyl ethers, and finally in absolute benzene — a-mercurated or α,β-dimercurated alkyl acetates. 3. The chemical properties of the organomercury compounds obtained have been studied and it was shown that: a) the dimercurated compounds of types (IV–VI) decompose on heating with concentrated hydrochloric acid with liberation of mercurous chloride and formation of the corresponding carbonyl compound; b) bromination of dimercurated compounds of types (IV–VI) with bromine and saturated aqueous potassium bromide solution in the cold leads to the formation of the corresponding α-bromoketone in addition to the ketone; c) the monomercurated compounds of types (I-III) decompose in concentrated alkali in the cold with liberation of metallic mercury and formation of the corresponding carbonyl compound.

The reaction of free radicals with asymmetric organomercury compounds

Abstract: 1. The reaction of asymmetric organomercury compounds with carbon tetrachloride proceeds via a radical mechanism in the presence of benzoyl peroxide. The less reactive group linked to mercury in RHgR' stays attached to mercury, but the more reactive group is converted into RCCl3. 2. A series has been established for radicals arranged in order of decreasing affinity towards the free radical CC13.
