Copper complexes generated in situ from CuCl2, alkyl Grignard reagents, and 1,3‐dienes play important roles as catalytic active species for the 1,2‐hydroalkylation of 1,3‐dienes by alkyl fluorides through CF bond cleavage. The alkyl group is introduced to an internal carbon atom of the 1,3‐diene regioselectively, thus giving rise to the branched terminal alkene product.
由CuCl 2,烷基格氏试剂和1,3-二烯原位生成的铜络合物作为催化活性物质,对通过烷基氟通过CF键裂解的1,3-二烯1,2-加氢烷基化起催化活性作用。烷基被选择性地引入到1,3-二烯的内部碳原子上,从而产生了支链末端烯烃产物。
