Montmorillonite K-10 was used in the acid catalysis of the Willgerodt-Kindler’s reaction (WK) under microwave heating for synthesis of thiobenzamides. Yields of 67% and 43% for the synthesis of morpholin-4yl (phenyl) methanethione (1) and [4 - (dimet [...]

This paper reports efforts aimed at tuning up the synthesis of a compound library centered on the general template 2amino-1-phenyl-2-thioxoethanonetakingthecondensationof [...]
A concise series of aldehydes and ketones were reacted in a condensation reaction with 4phenylthiosemicarbazide in order to assess the relative influence of the steric and electronic effects in the control of this reaction. While steric effects had a [...]
A reaction system is described to synthesize phenytoin, a major antiepileptic drug, and structurally related compounds using a two-step approach. The first step involves the treatment of a benzil derivative by thiourea in dimethylsulfoxide (DMSO) i [...]
The reaction of acenaphthone with morpholine and sulfur was studied in order to assess the effects of adding a source of acid or base in the Willgerodt-Kindler (WK) reaction. Addition of a strong acid was found beneficial particularly with Montmori [...]
