文摘

The synthesis of the new compounds 9-triptycyldimethyltin bromide (2) and 9-triptycyldimethyltinhydride (3) and some of their physical properties aredescribed. The radical addition of 3 to methyl (E)-2,3-diphenylpropenoate gave the threo adducts as the onlyproducts. The results obtained in the addition of hydride3 to mono- and disubstituted alkynes under radical andpalladium-catalyzed conditions indicate that these reactions take place with high stereoselectivity. The chemicalreactivity of these vinylstannanes is similar to that ofvinyltriorganostannanes containing smaller organicligands. Full ¹H, ¹³C, and ¹¹⁹Sn NMR characteristics areincluded.
