Significance

A very simple and convenient method for preparation of symmetrical biaryls and bis-heteroaryls from corresponding aryl- and hetaryl halides. Various functionalized Grignard reagents can be used in the reaction. The intra­molecular variant allows synthesizing interesting polycyclic systems.
