0-Aryl complexes from organoborons

Oxidative addition [1, 38] of 1-alkenyl, 1-alkynyl, allyl, benzyl, and aryl halides to a palladium(O) complex affords a stable trans-o-p al 1 adi u m( 11) complex (11). The reaction proceeds with complete retention of configuration for alkenyl halides and with inversion for allylic and benzylic halides. Alkyl halides having /5-hydrogens are rarely useful because the oxidative addition step is very slow and may compete with /5-hydride elimination from the <7-organopalladium(II) species. However, it has been recendy shown that iodoalkanes undergo the cross-coupling reaction with organoboron compounds (Section 2.4.5). [Pg.55]
