The first example of Pd-catalyzed Suzukicross-coupling of readily available arylhydrazines with arylboronic acids via C–N bond cleavage was developed under air, affording various biaryl compounds with broad substrate applicability and moderate to good yields. Moreover, the rigorous exclusion of air/moisture is not required in these transformations. Thus, the protocol represents a simple and efficient
iron-catalyzed cross-electrophile coupling of aryl chlorides with unactivated alkylchlorides via an iron/B2pin2 catalytic system has been developed. (Hetero)aryl chlorides undergo this transformation smoothly under mild conditions, furnishing the alkylated products with good efficiency. This protocol features excellent functional group compatibility and gram-scale synthesis, which also enables the late-stage functionalization
