Synthesis and Characterization of (Z)-Ethyl 3-(Salicylhydrazinocarbonyl) Propenoate
摘要
Abstract
To obtain a synthesis method of the esterification of carboxylic acid with bis-hydrazide, salicylhydrazide was prepared using methyl salicylate and hydrazine hydrate , followed by reaction with maleic anhydride to produce ( Z )-3-( salicylhydrazinocarbonyl ) propenoic acid ( ( Z )-H4 shcpa ) .A metallacrown system was then formed by reaction with FeCl3· 6H2O.The ligand was esterified and transformed into (Z)-ethyl 3-(salicylhydrazinocarbonyl) propenoate ((Z)-H3 eshcp) through internal self-catalytic reaction.The metallacrown can be treated with SnCl 2/HCl to obtain purified ester ( Z)-H3 eshcp in good yield .The structure of these compounds were characterized by IR , 1 H-NMR, 13 C-NMR and element analysis.It showed that the difficult problem of ethyl-esterification of carboxylic acid with bis-hydrazide can be solved through the internal self-catalytic reaction of metallacrown system .关键词
