  摘要：

  The 16-electron half-sandwich cobalt complex Cp"Co[Se2C2(B10H10)] (Cp" = eta(5)-1,3-Bu2C5H3) (3) has been synthesized by the reaction of [(THF)(3)LiSe,C2B10H10Li(THF)](2) (2) with Cp"Co(CO)I-2 (1). The hetero-binuclear complex Cp"CoW(CO)(2) [Se2C2(B10H10)](2) (4) was obtained from the reaction of 3 with W(CO)(3)(py)(3) in the presence of BF3 (.) Et2O.

  inexpensive and atom‐economical approach to CH bond functionalization, a cationic CoIII complex (see scheme) was used to generate nucleophilic organometallic species in situ without additional activating reagents. Under these conditions, aryl CH bonds underwent efficient addition to polar electrophiles, including α,β‐unsaturated N‐acyl pyrroles as β‐substituted ester and amide surrogates.

  活性而不活化：在一种廉价且原子经济的CH键官能化方法中，使用阳离子Co III配合物（请参见方案）在原位生成亲核有机金属物种，而无需其他活化剂。在这些条件下，芳基CH键要有效地添加到极性亲电体中，包括α，β-不饱和N-酰基吡咯作为β-取代的酯和酰胺替代物。
