A series of N-aryl and N-heteroaryl pyrazoles have been deproto-metallated using a 2,2,6,6-tetramethylpiperidino-based mixed lithium–zinc combination. Mono-, di-, and tri-iodides have been obtained after subsequent trapping with iodine, depending on the substrate and on the quantity of base used. The results have been discussed in the light of the CH acidities of the substrates, determined both in the gas phase and in THF solution using the DFT B3LYP method.

A general and efficient procedure for C−H alkenylation of arenes with a broad substrate scope catalyzed by Cp*CoIII was demonstrated with alkynes. A highly selective mono‐alkenylation and sequential bis‐C−H bond functionalization was displayed to exemplify the versatility of the cobalt catalyst. Isolation of cationic Cp*CoIII–alkenyl intermediate was achieved under identical catalytic conditions to
用炔烃证明了由Cp * Co III催化的具有广泛底物范围的芳烃的CH链烯基化的通用有效方法。高选择性的单烯基化和顺序的双CH键功能化显示了钴催化剂的多功能性。在相同的催化条件下实现了阳离子Cp * Co III-烯基中间体的分离,以进一步建立拟议的途径。
