摘要

Treatment of allyl 2-halophenyl ethers with tributylmanganate (n-Bu 3 MnLi or n-Bu 3 MnMgBr) provided dihydrobenzofuran derivatives in good yield. Indoline derivatives are also produced effectively starting from 2-iodoaniline compounds. The reaction could proceed by the following sequences:(1) formation of a radical by treatment of iodophenol or iodoaniline derivatives with tributylmanganate (II),(2) radical cyclization, and (3) ...
