Abstract

The interactions of sodium salts of 2-mercaptobenzoxazole, 2-mercaptobenzothiazole and 2-mercaptobenzimidazole with (chloromethyl)trimethyl-, chloromethyl(dimethoxy)methyl- or (chloromethyl)trimethoxysilanes have been shown to result in the corresponding previously unknown (2-heterylthiomethyl)triorganylsilanes. Transetherification of (2-heteryl-thiomethyl)trimethoxysilanes with triethanolamine gives 1-(2-benzoxazolylthiomethyl)-, 1-(2-benzothiazolythiomethyl)- and 1-(2-benzimidazolylthiomethyl)silatranes. The reaction of the corresponding alkoxysilaneswith boron trifluoride etherate leads to (2-benzoxazolythiomethyl)- and (2-benzothiazolylthiomethyl)-substituted trifluorosilanes and methyldifluorosilanes having a dragonoid chelate structure. By the hydrolysis of (2-heterylthiomethyl)trimethoxysilanes, new organosilicon sorbents, poly(2-heteryl-thiomethyl)silsesquioxanes have been synthesized.
