The LiCl-mediated Mg insertion into polysubstituted aryl chlorides bearing up to three chloro substituents in ortho or meta position selectively leads to Grignard reagents which readily react with variouselectrophiles. As an application, we have developed a new formal synthesis of boscalid. insertion - magnesium - lithium - aryl chlorides - boscalid
