dc.description.abstract |
A family of oxazaborines, diazaborinones, triazaborines, and triazaborinones was prepared by reaction of polarized ethylenes, such as beta-enaminoamides, with 4-methylbenzenediazonium tetraphenylborates. The reaction conditions (stirring in CH2Cl2 at room temperature (Method A) or stirring with CH3COONa in CH2Cl2 at room temperature (Method B) or refluxing in the CH2Cl2/toluene mixture (Method C)) controlled the formation and relative content of these compounds in the reaction mixtures from one to three products. Substituted oxazaborines gradually rearranged into diazaborinones at 250 °C. The prepared compounds were characterized by 1H NMR, 13C NMR, IR, and UV-Vis spectroscopy, HRMS, or microanalysis. The structure of individual compounds was confirmed by 11B NMR, 15N NMR, 1D NOESY, and X-ray analysis. The mechanism of reaction of enaminoamides with 4-methylbenzenediazonium tetraphenylborate was proposed. |

Reakcí polarizovaných ethylenů, konkrétně beta-enaminoamidů, s 4-methylbenzendiazonium-tetrafenylborátem byla připravena série oxazaborinů, diazaborinonů, triazaborinů a triazaborinonů. Reakčními podmínkami lze kontrolovat vznik jednotlivých produktů. Substituované oxazaboriny přechází na diazaborinony při 250 °C. Připravené sloučeniny byly charakterizovány 1H NMR, 13C NMR, IČ a UV-Vis spektroskopií, HRMS nebo elementární analýzou. Struktury produktů byly potvrzeny také 11B NMR,15N NMR, 1D NOESY a X-ray analýzou. Byl navržen také mechanismus reakce. |
