Abstract
2-(2-Propenoxy)phenyllithium (1), which may be prepared from the corre sponding iodide by low-temperature lithium-iodine exchange, rearranges on warming in the presence of TMEDA via 5-exo cyclization to (2,3-dih ydrobenzofuranyl)methyllithium (2) followed by gamma-elimination to gi ve variable amounts of the lithium salt of 2-(cyclopropyl)phenol (3).
