diphenylmercury, HgO, and Ni(acac)2(THF)2. With PhHgOH or PhHgSH the symmetrizationreactions also occurred when catalytic amounts of Ni(acac)2 were used. In contrast, triphenyltin derivatives (hydroxide, acetate, oxide) on treatment with M(acac)2 in aqueous THF gave the stable complexes [M(acac)2(Ph3SnOH)]2 (M = Co, Ni). The structure of [Ni(acac)2(Ph3SnOH)]2 (2) was also determined by X-ray crystallography

Abstract Organomercurials of 2-mercapto-5-methyl-1,3,4-thiadiazole and 2-mercapto-5-[4′-methyl quinolinyl-2-oxy methyl] -1,3,4-oxadiazole with aryl mercuric chloride have been synthesized under microwave irradiation in open vessels in a domestic microwave oven within a few minutes. This reaction rate was ca 100 times faster than the reaction rate in the conventional way. These organomercurials have a

The reaction of aryl or vinylic mercurials, Li2PdCl4 and vinylic β-lactams affords good yields of the corresponding ring-opened β,γ-unsaturated amides.

Aryl-, alkenyl-, and alkylmercurials readily cross-couple with primary and secondary alkyl- and alkenylcuprate reagents to provide the first truly general method for the alkylation of a wide variety of organomercurials.
Abstract Organomercury(II) complexes involving 6-thioguanine of the type p -XC 6 H 4 HgL ( I ) (LH = 6-thioguanine; X = Me, MeO, NO 2 ) have been synthesized. Spectral studies (IR and UV) indicate that the 6-thioguanine moiety acts as a bidentate group. From thermogravimetric (TG) curves, the order, activation energy and apparent activation entropy of the thermal decomposition reaction have been elucidated
