One-pot and catalyst-free synthesis of thiosemicarbazones via multicomponent coupling reactions
摘要:
A novel and efficient procedure for the synthesis of thiosemicarbazones has been achieved via a multi-component and catalyst-free reaction of phenyl or p-chlorophenyl isothiocyanate, hydrazine, and aldehydes or ketones. The method afforded 20 thiosemicarbazones in good yields and short reaction time. (c) 2009 Elsevier Ltd. All rights reserved.
