【摘要】 在固液相转移催化条件下,以PEG-400为催化剂,通过芳酰氯与硫氰酸铵反应合成了中间体芳酰基异硫氰酸酯;后者不需分离,直接与芳胺反应,高产率获得N-芳酰基-N′-(4-芳氧基苯基)硫脲衍生物.更多还原

【Abstract】 Aroyl isothiocyanate is synthesized by the reaction of aroyl chloride with ammonium thiocyanate under the condition of solidliquid phase transfer catalysis using PEG400 as the catalyst.The later need not to be isolated and reaction with aromatic amine immediately to give NarylN′(4aryloxyphenyl)thiourea derivatives in high yield.The promoting effects of the title compounds on wheat growth are tested preliminary.更多还原
