reveal an interesting and unexpected thermal instability which allows the convenient synthesis of carboxylic acid fluorides 5b–f. This procedure offers advantages over known methods: All operations can be performed in a standard glass apparatus and do not require highpressures. The formation of RCOF 5 is assisted by the pyridine moiety of 4, which splits off and functions as a Lewis base to intercept
