Aryl formates are prepared in a two step one-pot procedure from phenols. Firstly the formylating reagent triformamide (1b) is generated from sodium diformamide (2) and methane- sulfonyl chloridein situ, which reacts with phenols4a–fto give aryl formates5a–fin good yields. Triformamide, pre- paredin situ, transforms anisole in the presence of aluminum chloride to theN-(diarylmethyl)formamide7.

Key words:Aryl Formates, Formylation, Hydroxyarenes
