Abstract

Direct nuclear substitution of dibenzofuran permits introduction of mono-substituents in the 2- , 3-and 4-positions, but not in the 1-position. No ring-closure synthesis of a mono-1- substituted type has so far been successfu1. l We are now reporting syntheses of a number of simple and polyfunctional dibenzofurans having a substituent in the I-position.
