용도

Hexa-n-butylditin is used in palladium-catalyzed tin-carbon bond formation. It finds useful application in deoxygenation and desulfurization reactions. It acts as a source of tributylstannyl radicals in synthetic chemistry. It is also used in the radioiodination of styrlpyridines. Further, it is used as a reagent to stannylate aryl halides for further Stille coupling.

참고

Incompatible with strong oxidizing agents.

Source of on thermolysis or photolysis of tributylstannyl radicals, avoiding the problems sometimes attributable to the hydrogen donor capability of Tri-n-butyl­tin hydride, A13298 .ɑ-Iodo ketones or esters with a suitably-placed double bond undergo radical cyclizations on UV irradiation in the presence of a catalytic amount of the distannane: Tetrahedron Lett., 28, 2477 (1987); J. Org. Chem., 54, 1826, 3140 (1989). Compare analogous reductive cyclizations using the tin hydride. Improved conditions have been developed for generation of the tributylstannyl radical by mild UV irradiation in the presence of a triplet sensitizer (e.g. 4'-Methoxyacetophenone, A11162 ), allowing selective C-C bond forming reactions to be performed under free-radical conditions: Synlett, 287 (1993).
