An efficient and high-yielding cross-coupling reaction of various primary, secondary, and tertiary alkyl chlorides with aryl Grignard reagents was achieved by using catalytic amounts of N-heterocyclic carbene ligands and iron salts. This reaction is a simple and efficient arylation method having applicability to a wide range of industrially abundant chloroalkanes, including polychloroalkanes, which
通过使用催化量的N杂环卡宾配体和铁盐,可以实现各种伯,仲和叔烷基氯与芳基格氏试剂的高效且高产率的交叉偶联反应。该反应是一种简单有效的芳基化方法,其适用于广泛的工业上丰富的氯代烷烃,包括聚氯代烷烃,在常规的交叉偶联条件下,这些化合物对底物具有挑战性。
