Abstract
The reaction of hydrazine hydrate with 1-diazo-3-, 1-diazo-4-, and 1-diazo-5-phthalimidoalkan-2-ones containing a substituent at the ..cap alpha.. position to the phthalimide group in the hydrocarbon chain leads to the formation of 1-diazo-3- and 1-diazo-4-(2-hydrazidophenylcarbamoyl)alkan-2-ones. On heating in the presence of an excess of hydrazine hydrate the reaction products are 1-diazo-3-, 1-diazo-4-, and 1-diazo-5-aminoalkan-2-ones. Various 1-diazo-3-, 1-diazo-4-, and 1-diazo-5-arenesulfamoyl-alkan-2-ones were synthesized in the reaction of arenesulfonyl chlorides with 1-diazo-3-, 1-diazo-4-, and 1-diazo-5-aminoalkan-2-ones in the presence of triethylamine.
