The bulk chemicals esters contribute to commodity chemicals in nearly unlimited variety. Common fields of application include their use as solvents, plasticizers, surfactants, flavours, inter mediates in preparative organic chemistry, and many more.1 Though well investigated, the technology of ester production offers some challenging characteristics regarding catalysis, operation conditions and...
متن کاملSyntheses of calix[4]pyrroles by amberlyst-15 catalyzed cyclocondensations of pyrrole with selected ketones.
A facile and efficient protocol is reported for the synthesis of calix[4]pyrroles and N-confused calix[4]pyrroles in moderate to excellent yields by reaction of dialkyl or cycloalkyl ketones with pyrrole catalyzed by reusable Amberlyst(TM)-15 under eco-friendly conditions.
متن کاملTellurium in Organic Synthesis, IX [15] Oxidation of Some Nitrogenous Compounds with Te02
The reaction between bis(p-methoxyphenyl)telluroxide and various substituted phenylhydrazines has recently been reported [1]. In this reaction the phenylhydrazines are converted to the corresponding hydrocarbons and nitrogen, also producing bis(p-methoxyphenyl)telluride and an unsymmetrical telluride, resulting form aryl exchange. As a part of our investigation of the reactions of tellurium dio...
