Cross-homo scrambling

Some additional results of Pd-catalyzed allyl-allyl coupling are summarized in Table 3. In cases where regioisomerization, stereoisomerization, and/or cross-homo scrambling are... [Pg.592]

In contrast to the efficient and widely apphed palladium-catalyzed C(sp)-C(sp ) cross-coupling, palladium-catalyzed C(sp)-C(sp) and C(sp)-C(sp ) cross-couplings remain largely underdeveloped. Furthermore, they are hampered by side reactions. In the first case, competitive cross-homo scrambling is problematic. In the second case, as oxidative addition is slower in the case of C(sp )-electrophiles, competitive oxidative homo-coupling of the alkynylzinc partner becomes important It is thus limited to activated electrophiles. [Pg.320]
