Mercury iodomethyl

Methylene iodide, on the other hand, when left in contact with metallic mercury and some mercurous iodide in a sealed tube for four or five days, combines with the mercury. Two products are produced, but no gas is evolved when the tube is opened. The first compound crystallises from boiling alcohol in slender, wdiite needles it is best purified by solution in methylene iodide and precipitation with ether, and is insoluble in the usual solvents. Sakurai assigned the formula I-CHg -Hgl to the substance. This monomercuric methylene iodide or iodomethyl mercuric iodide when heated with iodine in potassium iodide solution yields methylene iodide and mercuric iodide, and similar decomposition takes place with chlorine or bromine.

Reaction of bis(trimethylsilyl)acctylene with (iodomethyl)mercury(II) iodide and diphenylmer-cury gave a low yield (10%) of 1.2-bis(trirnethylsilyl)cyclopropenc as a clear oil which rcsinified on standing at ambient temperature.Addition of trimethylsilylcarbene, generated from chloromethyltrimethylsilane and lithium 2,2,6,6-tetramethylpipcridide occurred in 15% yield to give the cyclopropene 1 as an oil which was stable for about a month at ambient tempera-ture." - ...

Preparative Methods several methods for the preparation of bis[(trimethylsilyl)methyl]zinc have been reported. Addition of powdered anhydrous zinc(II) chloride to a solution of [(trimethylsilyl)methyl]magnesium chloride in diethyl ether at 0 °C and subsequent stirring for 4 days at room temperature affords the title compound in 90% yield after fractional distillation. A second route consists of the reaction of (iodomethyl)tri-methylsilane with zinc/copper couple (prepared by reduction of CuO with dihydrogen in the presence of zinc dust) at reflux for 3 h and affords the title compound in 56% yield. Bis[(trimethylsilyl)methyl]zinc can also be prepared quantitatively by reacting bis[(trimethylsilyl)methyl]mercury with an excess of zinc at ambient conditions. ...
