Initial screening experiments revealed that acetonitrile leads to a smaller extent of desilylation and better regioselectivities than other solvents (DMF, NMP, dioxane, and DMSO) for this particular reaction, for a recent discussion of the palladium-mediated mechanism of desilylation, see: LaPointe, A. M.; Rix, F. C.; Brookhart, M. J. Am. Chem. Soc. 1997, 119, 906. See also ref 6h.

As regards the desilylation process, a higher degree of desilylation takes place as the temperature rises but the desilylation is brought about in the product-forming stage of the reaction and does not change markedly thereafter, suggesting that the desilylation is palladium-mediated. See also refs 4 and 6h.

The microwave technique lends its efficiency mainly from the fact that a polar, homogeneous reaction mixture will be heated faster under microwave irradiation than under thermal heating. Apart from this, the boiling point elevation due to pressure in a closed Pyrex tube allows higher temperatures than are ordinarily feasable. (a) Hájek, M. Collect. Czech. Chem. Commun. 1997, 62, 347.

The fact that minute amounts of the unbranched 3-aryl-1-propene, possibly derived from a concomitant Stille reaction, was observed by NMR made an accurate determination of the regiocontrol difficult. The heavier elements in the group (Sn and Pb) have been reported to be more easily displaced than the lighter elements (Si and Ge). For a discussion of this phenomenon, see ref 6c. Internally arylated allylstannane compounds are unstable; see: Desponds, O.; Schlosser, M. J. Organomet. Chem. 1991, 93.
