Synthesis of N—Aroyl—N′—hydroxyethyl (Hydroxyphenyl) Thiourea Derivatives Under the Condition of Phase Transfer Catalysis
摘要:
Reaction of aminoethanol. or aminophenol with aroyl chloride and ammonium thiocyanate under the condition of solid-liquid phase transfer catalysis using polyethylene glycol-600 (PEG-600) as the catalyst yielded N-aroyl-N'-hydroxyethyl (hydroxy phenyl) thiourea derivatives.The products have been characterised on the basis of analytical and spectral(IR and 'H-NMR)data.

A series of N-aroyl-N ' -substituted thiourea derivatives have been prepared in good to excellent yields under the condition of solid-liquid phase transfer catalysis using polyethylene glycol-400(PEG-400) as the catalyst. The products have been characterized on the basis of analytical and spectral (IR and H-1 NMR) data. The promoting effects of some compounds on wheat growth have been tested preliminary.
