Phase-Managed Organic Synthesis. A New Synthesis of Mixed Formic Anhydrides

Article abstract of DOI:10.1021/jo00369a048

Two new mixed formic anhydrides, cinnamic formic anhydride and formic 4-methoxybenzoic anhydride, can be prepared in high yield ( c.a. 80percent) from equimolar mixtures of sodium formate and the appropriate acid chloride with a solid-phase copolymer of pyridine 1-oxide as catalyst, and they exhibit excellent selectivity as formylating agents of alcohols and amines
