Full quantum chemical calculations with density functional theory (DFT) show that bond-strengthening back-donation to a π-diborene, recently discovered for transition metal systems (Braunschweig and co-workers, Nat. Chem., 2013, 5, 115–121), would be just as favored for Main Group silylene complexes.

This article describes the synthesis and tautomerism of 2- (4,6-dioxo-1,3,5-triazinan-2-ylidene) hydrazinecarboxyamide. The synthesized compound was investigated using elemental analysis methods, and quantum chemical calculations performed in ChemCraft 1.8 and Gaussian programs. Composite methods of the Gaussian family (G4) and density functional theory (DFT) methods (BLYP / 6-311 + G (d, p)) were used. The data obtained indicate that the BLYP / 6-311 + G (d, p) well suited for describing such systems in order to save 66 machine resources. Based on the calculated resistance series, it was established that the main form is diketoenolform.
