Palladium complex-catalyzed germylation of allylic halides using (germyl)stannanes

(Triethylgermyl)tributylstannane reacts metal-selectively with allylic halides at room temperature (r.t.) in the presence of tris(dibenzylideneacetone)dipalladium, Pd2(dba)3CHCl3, to provide an alternative route to allylgermanes. (Dimethylphenylgermyl)tributylstannane regio- and stereoselectively reacts more readily with allylic halides than (triethylgermyl)tributylstannane affording the corresponding allylgermanes in quantitative yields.
