Dimethylmercury

Im scared shitless of this stuff, but I dont know if it is produced when in the presence of dimethyldioxane. Could someone describe if any the reactions that could occur?

I'm scared shitless of it, too, so I take the easy route and simply not work with mercury compounds.

In what circumstances?
I'm fairly sure that reacting mercuric chloride with methylmagnesium bromide in dimethyl dioxane would produce it.
But I'm even more certain that it wouldn't be produced if there was no mercury or mercury compound present in the system.

sodium amalgam and methyl iodine

The American Occupational Safety and Health Administration advises handling dimethylmercury with highly resistant laminated gloves with an additional pair of abrasion-resistant gloves worn over the laminate pair, and also recommends using a face shield and working in a fume hood.

But my question is "Why?". What can you do with Me2Hg that can't be done by many other safer chemicals, like a Grignard reagent or one of the much less toxic M (Me)x compounds?

Maybe why he is asking is because he wants to use dimethyldioxane as a solvent for a reaction involving mercury and doesnt want dimethylmercury to form? Idk though

Dimethyldioxane will not methylate mercury (or anything). In fact, ethers will chelate many organometallic compounds.
