2-Trimethylsiloxy- and 2-trimethylsilylthio-1,3-diaza-1,3-butadienes, formed on reaction of trimethylsilylimines with isocyanates and isothiocyanates R2-N=C=X (X=O, S), react with isocyanates to give high yields of substituted 5,6-dihydro-1,3,5-triazine-2,4(1H,3H)-dione and 4-thioxo-3,4,5,6-tetrahydro-1,3,5-triazin-2(1H)-one derivatives.
