Organometallic reactions. Part XVII. Some exchange and addition reactions of aminodimethyltin compounds
Dimethyltin bis(diethylamide) reacts with dimethyltin dihalides to produce the dimethyltin halide diethylamides; these are unstable, but can be characterised as their adducts with carbon disulphide.
NN′N″-Triethylhexamethylcyclotristannazane, (Me2Sn·NEt)3, disproportionates when treated with organotin chorides, RnSnCl4–n, to give distannazanes of general formula RnSnCl3–n·NEt·SnMe2Cl. Treatment of 1,1,3-trichloro-2-ethyl-1,3,3-trimethyldistannazane with 2,2′-bipyridyl gives Me2SnCl2, bipy and sym-trichloro-NN′N″-triethyltrimethylcyclotristannazane. A mixture of dimethyltin sulphide and the triethylhexamethylcyclotristannazane exists in equilibrium with the cyclotristannazadithiane and the cyclotristannadiazathiane.
