Fluoromethyl ethers of various functionalized phenols were synthesized from the corresponding methylthiomethyl ethers by the reaction with IF5-pyridine-HF. A fluoromethyl ether of an aliphatic alcohol and a fluoromethyl ester of a carboxylic acid were also synthesized.

A conceptually intuitive synthesis of oxothioacetals is reported starting from thiosulfonates as electrophilic sulfur donors. The installation of a reactive CH2Cl motif with a homologating carbenoid reagent, followed by the immediate nucleophilic displacement with alcoholic groups [(hetero)‐aromatic, aliphatic] offer a convenient access to the title compounds. Genuine chemoselectivity is uniformly
