Sulphamic Acid as an Efficient Catalyst for Synthesis of Thiosemicarbazone Derivatives at Room Temperature
Author(s): Tryambake PT
Various thiosemicarbazone derivatives have been prepared from thisemicarbazide and substituted aromatic aldehyde in presence of sulphamic acid as mild, efficient, inexpensive, nontoxic catalyst and cost-effective catalyst at room temperature. It provides the products in excellent yields and in much shorter reaction time.
