A sequential nucleophilic addition/ring contraction of α-bromo N-iminolactam with organometallic reagents for the synthesis of 2-acyl pyrrolidines has been developed. The reaction allows facial construction of 2-acyl pyrrolidines incorporating not only ar

Migratory carbometalation: A cobalt-Xantphos complex catalyzes the addition of an arylzinc reagent to an unactivated internal alkyne; the reaction most likely involves insertion of the alkyne into an arylcobalt species and vinyl-to-aryl 1,4-cobalt migration, followed by transmetalation with the arylzinc reagent. Interception of the resulting ortho-alkenylarylzinc species with electrophiles allows access to 1-alkenyl arenes functionalized in the 2-position. Copyright
