A method by which a halogen atom of a halogen compound can be efficiently replaced with an electrophilic group.
Also provided are: a reagent for converting a functional group through a halogen-metal exchange reaction, characterized by comprising either a mixture of a magnesium compound represented by the formula R
1
—Mg—X (I) (wherein R
1
represents a halogen atom or an optionally substituted hydrocarbon residue; and X
1
represents a halogen atom) and an organolithium compound represented by the formula R
2
—Li (II) (wherein R
2
represents an optionally substituted hydrocarbon residue) or a product of the reaction of the magnesium compound with the organolithium compound; and a process for producing with the reagent a compound in which a halogen atom of a halogen compound has been replaced with an electrophilic group.
一种通过卤素化合物的卤素原子有效地被电亲团取代的方法。还提供了:一种用于通过卤金属交换反应将功能团转化的试剂,其特征在于包括由表示为R1—Mg—X(I)的镁化合物的混合物(其中R1表示卤素原子或可选择地取代的碳氢残基;X1表示卤素原子)和由表示为R2—Li(II)的有机锂化合物(其中R2表示可选择地取代的碳氢残基)组成,或者是镁化合物与有机锂化合物反应的产物;以及使用该试剂制备一种化合物的过程,其中该化合物的卤素化合物的卤素原子已被电亲团取代。
