Abstract
The ylides Ph3E-C6H6N2O3 (7, E = P (a), As (b), Sb (c)) have been prepared through the reaction of Ph3E and 5- bromo-1,3-dimethyl-2,4,6(1H,3H,5H)-pyrimidinetrione (5-bromo-1,3-dimethylbarbituric acid) 6 in the presence of triethylamine. Their characterisation was performed by nuclear magnetic resonance (NMR), mass spectrometry (MS) and elemental analysis.
Keywords: 1,3-dimethyl-2, 4,6(1H,3H,5H)-pyrimidinetrione (1,3-dimethylbarbituric acid), nuclear magnetic resonance, synthesis, zwitterionic state
