Since the mercury-carbon bond is not disturbed in any way in this reaction, one (and only one) of the 5-butyl groups in the di-5-butylmercury should have an optically active center. The mercury exchange reaction of Equation 4.49 was then carried out on the di-j-butylmercury thus formed, and the optical rotation... 

When solid mercury carbonate, Hg2C03, is added to nitric acid, HN03, a reaction occurs to give mercury ) nitrate, Hg(N03)2, water, and two gases A and B ... 

Other ions studied include the cyclohexene- and norbomylene-mercurinium ions. N.m.r. studies show deshielding of both protons and carbons, indicating charge transfer from mercury to the carbon skeleton both mercury-proton and mercury-carbon spin-spin couplings are observed. Some of the spectra are best interpreted in terms of an equilibrium between the mercurinium ion and the free olefin. Quenching experiments are consistent with the presence of mercurinium ions. 

The 13C spectra of some (3-methoxyalkyl mercuric chlorides have been reported.175 The results indicate that (Hg-C) ( 1600—1800 Hz) varies in direct proportion to the increase in electron density at the mercury-carbon bond, and that an increase in mercury-carbon alkyl substitution, an effect which is in direct contrast to that observed for platinum 7r-olefin complexes. 

The mercury-carbon bond of this bicyclic ketone is fastened almost perpendicularly to the plane of the carbonyl 77-orbital. This perpendicularity may be solely responsible for the fact that the compound, unlike the a-mercurated open-chain 0x0 compounds, possesses a quite inactive mercury atom. While the compounds ClHgCH2C(0)R are instantaneously hydrolyzed or alcoholyzed in the presence of I , and readily react with triphenylchloromethane or with acyl chlorides, a-chloromercuricampheni-lone reacted neither with these agents nor even when refluxed with concentrated hydrochloric acid for a long time. Together with Kursanov, Pecherskaya, and Parnes 121) we studied deuterium exchange in cam-phenilone and camphorquinone... 

Reduction of the phosphorus-carbon bond is generally achieved with the aim of preparing new phosphorus compounds, and not with the object of preparing reduced carbon compounds. It is a striking difference from mercury-carbon bond cleavage, which is usually carried out in order to prepare carbon compounds. 

Scheele studied the effect of heat on a number of different compounds. In one experiment, he used silver carbonate (Ag2C03), mercury carbonate (HgC03), magnesium nitrate (Mg (N03)2). When he heated these compounds,...
