Synthesis of 5-alkyl-1,3,5-triazinan-2-ones and 5-alkyl-1,3,5-triazinane-2-thiones using Cu- and Sm-containing catalysts
摘要:
Efficient procedures have been developed for the synthesis of 5-alkyl-1,3,5-triazinan-2-ones and 5-alkyl-1,3,5-triazinane-2-thiones by reaction of urea (thiourea) with primary alkylamines and N,N,N',N'-tetramethylmethylenediamine and by reaction of primary amines with N,N'-bis(dimethylaminomethyl)urea(thiourea) in the presence of Cu- and Sm-containing catalysts.
