Abstract
Abstract Tributenyltin compounds containing double bonds at C-1 or C-3 or combinations thereof are synthesized from symmetrical tetrabutenyltins to offer a sufficient toxicity to function as a biocide or an antifoulant compound for ships' hulls and have an increased rate of degradation to be compatable with the environment.
