Alkynyl derivatives of benzofuran

Chemistry of Heterocyclic Compounds, 1972
A general method for the preparation of alkynyl derivatives of benzofuran, including α-ethynylbenzofuran, consists in the cyclization of o-mono-and dialkynylphenols under the conditions of the Mannich and Cadiot-Chodkiewicz reactions.

Ionic hydrogenation of benzofurans

Chemistry of Heterocyclic Compounds, 1975
Benzofurans are arranged in the order 2-methylbenzofuran > 3-methylbenzofuran > benzofuran with respect to the case with which they undergo ionic hydrogenation. Benzofuran and 2-methylbenzofuran are protonated in the 3 position of the heterocyclic ring, whereas 3-methylbenzofuran is protonated in the 2 position.
