摘要
New series of substituted aminothiadiazolylhydrazonoindolin-2-ones were prepared in high yields (89-94%) via the cyclocondensation of thiocarbonohydrazides (1a, 1b, 1c, 1d) with 3-(dicyanomethylene)-2-indolone in (ethanol/piperidine) at room temperature. Explanations of these conversations involve the nucleophilic addition on the dicyanomethylene carbon atom. The structures were established by spectroscopic data and single crystal X-ray crystallography.
