Mercury compounds tris metals

Garbometallation of carbon-carbon unsaturated bonds is an important synthetic method for the construction of complex molecules.277-281 An example of carboindation is described with tri(5-hexenyl)indium, prepared from di(5-hexenyl)mercury and indium metal, which is cyclized to a cyclopentylindium compound.282... 

Jordan and coworkers have recently prepared several ansa-bis(indenyl) compounds (AlMe2L)indenyl 2SiMe2 and 1,2- (AlMe2L)indenyl 2C2H4 (L = THF, Et20, 1,4-dioxane) by a salt metathesis route. These were reacted with M(NMe2)4 (M = Zr, Hf) to eliminate [Me2AlNMe2]2 and form ansa-metallocene complexes of bis(dimethylamido)zirconium and bis(dimethylamido)hafnium. A simple tris(indenyl)aluminum compound has been prepared by reaction of bis(indenyl) mercury with aluminum metal. ... 

Many of the salts which have been prepared are explosive and sensitive to heat or impact. These include chlorites of copper (violent on impact), hydrazine (monochlorite, inflames when dry), nickel (explodes at 100°C but not on impact), silver (at 105° or on impact), sodium, tetramethylammonium, mercury, thallium and lead (which shows detonator properties). Several other chlorites not isolated and unstable in solution include mono-, di- and tri-methylammonium chlorites. The metal salts are powerful oxidants [1], Chlorites are much less stable than the corresponding chlorates, and most will explode under shock or on heating to around 100°C [2], Individually indexed compounds are ... 

As mentioned earlier, the carbene ligand in our complexes shows nucleophilic character with respect to the metal fragment. Therefore, we decided to combine it with an electrophilic carbene. For this purpose we treated pentacarbonyl[methoxy(phenyl)carbene]chromium(0) with phenyl(tri-chloromethyl) mercury (85). Compounds of this kind have been studied intensively by Seyferth et al. (86) and are known as a source of dihalogeno-carbenes. The carbene complex reacted with the carbenoid compound at... 

In the initial studies about the reaction of /V.zV-disubstituted formamides with alkaline metals to give glyoxylic amides, the participation of carbamoyl metal derivatives as intermediates was postulated83. The first preparation of the carbamoyllithium 77 was described two years later by a mercury-lithium transmetallation from compound 76 at —75 °C (Scheme 20)84. The authors proposed also an aminocarbene structure 78 and studied its reactivity with methanol, methyl iodide, carbonyl compounds, esters, acyl chlorides, mercury(II) chloride and tri-n-butyltin chloride providing compounds 79. 

These results enabled us (34) to prepare several bridged compounds having two different metals. One of these was di-M-bromo-dibromobis(tri-n-propylarsine)mercury(II)palladium(II) (LXI), in which the palladium portion is of course planar and the mercuric portion is tetrahedral.
