Synthesis and Structure of 3-Aryl-5-cyano-6-methylthio pyrimidine2,4-diones
摘要:
The title compounds of 3-aryl-5-cyano-6-methylthiopyrimidine2.4-diones weresynthesized by the reaction of ethy1 2-cyano-3.3'dimethylthioacrylate with arylureas.The compound (Ar=p-CH3OC6H4) was recrystallized in acetone/petroleum in space group P2(1/n) with a=1.1602 (2), b=1.5921(3), c=1.3918 (3)nm.β=94.38 (3)° for Z=8.R=0.054.The X-ray analysis showed that there is H-bond interaction among molecules.
