, p. 85 - 94 (2007/10/02)
α-CF3S-substituted β-ketoacidamides, nitriles, thioamides and their Schiff bases are synthesised and their reactions with oxalyl chloride are investigated.As a new phenomenon the elimination of the CF3S group during cyclisation to substituted 2,3,5-trioxo-1,4-oxazepine (7), 4-pyrroline-2,3-dione (9) and oxalyl (10) is observed.Factors influencing this course of the reaction and mechanism of product formation are discussed.

Condensation of benzoylacetic acid amide and its imino derivative with oxalyl chloride yielded furan-2,3-dione 1 and 1H-pyrrole-2,3-dione 2 derivatives, respectively.The structure of the latter was proved by an analogous condensation of β-aminocinnamic ni
