On the stille vinylation reactions with α-styryltrimethyltin

Article abstract of DOI:10.1016/S0040-4039(97)01026-5

Stille vinylation reactions involving α-styryltrimethyltin 3b and a series of chloro- or bromo-pyridine derivatives are described. In contrast to the rare cine selectivity observed with iodobenzene 10a or 3-iodotoluene 10b, reactions between vinyltin 3b and a series of 2-halopyridine derivatives 15(a-d) yield 1,1-disubstituted ipso-coupled olefins 16(a-d) as the predominant products.
