1.Trialkyl-substituted chloro-, bromo-, and iodosilanes easily exchange a halogen atom for a mercury-salt anion during reaction with mercury acetate, benzoate, and cyanide. The reactivity in this reaction increases in going from chlorosilanes to bromo- and iodosilanes. Trialkylfluorosilanes and also trialkylalkoxy- and trialkylacetoxysilanes and hexaalkyldisiloxanes do not react with mercury salts, even during prolonged heating (up to 8 h at temperatures up to 125°C).2.The reaction of mercury salts with hexamethyldisilazane, N-organylhexamethyldisilazanes, trimethylsilyl(diorganyl)amines, and tris(trimethylsilyl)amine proceeds under mild conditions and gives acetoxymercuramines R3-nN(HgY)n, in high yields, where R=H, alkyl, or aryl and n=1, 2, or 3
