摘要
以1-苯基-3-甲基-5-氯-4-吡唑甲醛为原料,经氧化、酰氯化,然后在PEG-400催化下与硫氰酸铵及酰肼进行相转移反应,合成了一系列新化合物N-(1-苯基-3-甲基-5-氯-4-吡唑甲酰基)-N′-酰胺基硫脲,收率大于80%.题述化合物经元素分析、IR、1H NMR确证了结构.
A series of new compounds N-(1-phenyl-3-methyl-5-chloro-4-pyrazoformyl)-N'-acylthi- osemicarbazides were synthesized from 1-phenyl-3-methyl-5-chloro-4-pyrazole aldehyde via oxidation, chlorination,reaction with ammonium thiocyanate and then acylhydrazine in the presence of polyethy- lene glycol-400(PEG-400)as PTC catalyst.The structures of these compounds were confirmed by ele- mental analysis,IR and ~1H NMR.
