Fluorinated alkyl groups (Rp) can be radically attached to Ggp, for example by reaction of mercury-alkyl compounds under irradiation [10, 24] or by reaction with fluorinated alkyl iodides or bromides [25, 26]. Photochemical reaction with (R3Sn)2 or thermal reaction with RjSnH generates the Rp radical from the corresponding iodides or bromides. 

Magnesium haUde and alkyl magnesium haUde precipitate and the alkyl magnesium compound remains in solution. Filtration (qv) followed by drying the filtrate yields soHd magnesium alkyl (11). Another preparation method is that of metal exchange using mercury alkyl in ether. 

Many organometallic compounds are best prepared by this reaction, which involves replacement of a metal in an organometallic compound by another metal. The compound RM can be successfully prepared only when M is above M in the electromotive series, unless some other way is found to shift the equilibrium. That is, RM is usually an unreactive compound and M is a metal more active than M. Most often, RM is R2Hg, since mercury alkyls are easy to prepare and mercury is far down in the electromotive series." Alkyls of Li, Na, K, Be, Mg, Al, Ga, Zn, Cd, Te, Sn, and so on have been prepared this way. An important advantage of this method over 12-36 is that it ensures that the organometallic compound will be prepared free of any possible halide. This method can be used for the isolation of solid sodium and potassium alkyls." If the metals lie too close together in the series, it may not be... 

Several organolithium compounds have important apphcations in organic syntheses. These may be readily synthesized by reactions of lithium with organics. The metal reacts with alkyl or aryl halides or mercury alkyls or aryls to produce alkyl or aryl hthium. Some examples are ... 

A number of organometallic compounds show promise for LCEC study, and a few have already been examined in detail (especially mercury alkyls) [9]. More highly conjugated organic compounds such as a,a-unsaturated ketones and imines are occasionally good candidates, but at this time UV detectors frequently outperform electrochemical detectors for such systems. At this writing there have been only a few reported LCEC studies of metal ions or metal complexes. Perhaps the major reason for this is that very little modern LC has been carried out on them using any detector. It is difficult to compete with atomic spectroscopy techniques for the determination of most elements, but as speciation becomes more important, it seems likely that more LCEC methods will be developed for metal complexes. 

Using electrolytes containing (besides other substances) this system, and using a mercury cathode for protecting the metal alkyls obtained at the anodes against the very active sodium, rather nicely working new electrolytical processes for making alkyl compounds of lead and other metals have... 

The photooxidation of mercury alkyls is difficult to elucidate in that complicating reactions of mercury and the alkyl compounds themselves tend to obscure the simple oxidation of alkyl radicals. Martin and Noyes00 found that with mercury dimethyl they did not find formaldehyde to be a principal product of the photooxidation above 100°C. The reason is not obvious, but probably reflects the unsatisfactory nature of mercury dialkyls for studying the oxidation of alkyl radicals. 

Organoaluminum compounds, particularly AlEt3, are commercially very important as activators for olefin polymerization catalysts and are produced on a large scale, in spite of their pyrophoric nature and violent reaction with water. In the laboratory organoaluminum compounds can be made from mercury alkyls by transmetallation ...
