A tri-organotin silatrane derivative represented by the general formula (I) ##STR1## wherein the R.sup.1 groups are identical or different and each represents an alkyl, cycloalkyl, aryl or aralkyl group, R.sup.2, R.sup.3 and R.sup.4 are identical or different and each represents a hydrogen atom or a lower alkyl group, and m is a number of 2 or 3. The tri-organotin silatrane derivatives of the formula (I) are prepared by subjecting a 1-mercaptoalkylsilatrane and a tri-organotin hydroxide or bis(tri-organotin) oxide to a dehydration reaction, or reacting a 1-mercaptoalkylsilatrane derivative with a tri-organotin halide in the presence of a dehydrohalogenation agent, or subjecting a trialkoxysilane and a trialkanolamine to an ester-interchange reaction in the presence of an alkaline catalyst. The tri-organotin silatrane derivatives of the formula (I) are useful for an agricultural-horticultural pesticide, an industrial fungicide, an epidemic-preventing insecticide or an antifouling agent.
