The preparation of a library of 5-substituted-2-amino-1,3,4-oxadiazoles, e.g., I, and the corresponding thiadiazole analogs is reported. A one-pot preparation of the 2-aminosulfonylated analogs through a three component coupling of an acylhydrazine, an isocyanate and sulfonyl chloride promoted by a polymer-supported phosphazine base under microwave dielec. heating is presented. The optimization process and details pertaining to the elucidation of the reaction products is also discussed. In the experiment, the researchers used many compounds, for example, 3-Cyanophenylisocyanate (cas: 16413-26-6Related Products of 16413-26-6).
3-Cyanophenylisocyanate (cas: 16413-26-6) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
