Abstract Propargylic ethers serve as useful intermediates for the synthesis of a variety complex targets. However, propargylic substitution prefunctionalized alkyne starting materials remains dominant method propargyl ethers, while direct etherification simple alkynes via C−H functionalization largely underreported. Herein, we report an organometallic umpolung approach iron‐mediated etherification. A telescopic protocol deprotonation followed by mild oxidative coupling with alcohols enabled use or functionalized expedient excellent functional group compatibility, chemoselectivity and regioselectivity.

An efficient hydrogen bond-mediated alcoholysis of primary amides was disclosed using diethyl phosphonate (DEP) as a catalyst. In this process, wide range and alcohols were tested smoothly transformed to corresponding esters in moderate good yields. This novel strategy features transition metal-free, broad substrate scope one-pot pathway. addition, the reaction showed highly chemoselective o/alcoholic o-acylation mercapto/phenolic alcohols.
