Ein Beitrag zur Chemie des 2,3-Dihydro-3-oxo-benzothiophen-1,1-dioxids Synthesen mit Nitrilen, 86. Mitt.

2,3-Dihydro-3-oxo-benzothiophen-1,1-dioxide (1) reacts as CH-acidic component with amidines of orthoesters and anilines resp. to give the anilinomethylene derivates 3, 4, and 5.With triethyl orthoformiate the hydroxymethylene-compound 7 is obtained.Ani

Reactivity of 2,3-Dihydrobenzothiophene-3-one-1,1-dioxide

The benzothiophene-1,1-dioxides 2a-d and 3a-c react on warming to 2,3-dihydrobenzothiophene-3-one-1,1-dioxide (1).Compound 1 react with Amines, Hydrazines and Triphenylphosphoranes to give the condensationproducts 4, 7, and 9.With HN3 the Lactam 5 is formed.
