Abstract

Alkylene-, arylene- or benzylene-bridged ditin hexachlorides were obtained in high yields from the reaction of the corresponding hexacyclohexylated compounds with tin tetrachloride. These intermediates were successfully transformed into the corresponding alkynides, which gave gels of hybrid materials on hydrolysis. This is the first example of a gel formation from a organometal with the metal fully substituted with covalently-linked organic groups. Subsequent thermal treatment led to mesoporous tin oxide with high surface area and narrow pore size distribution.
