    • Incomplete reactions were always observed with an equimolecular amount of iodobenzene. On the other hand, other electrophiles, such as bromobenzene and phenyltriflate, were also used in these Heck reactions. However, these electrophiles were much less reactive than iodobenzene; they gave low conversions and therefore very poor yields of Heck products.

    • Taking into account that the best diastereoselectivities in the Heck arylations of alkenes 4 and 8 were obtained in the presence of bidentate phosphines, the participation of pentacoordinate palladium intermediates, instead of the tetracoordinate complex D, cannot be ruled out. For asymmetric Heck reactions that involve five-coordinate palladium intermediates, see: a) A. Ashimori, B. Bachand, L. E. Overman, D. J. Poon, J. Am. Chem. Soc. 1998, 120, 6477;

    • Unlike the case of the sulfinyldihydrofurans, the reaction of sulfinylcyclopentane 14 with activated zinc gave exclusively the corresponding thioether instead of the C-S cleavage product.
