The direct reaction between 2-nitroresorcinol and acetaldehyde in alkaline medium yields tetranitro-C1-resorcin[4]arene in a moderate 8.2% overall yield which was characterized by single crystal X-ray crystallography, 1H NMR spectroscopy and electrospray ionization mass spectrometry (ESI-MS). In solution and in the solid state, the product adopts a unique, thermally stable and unprecedented rcct-boat
2-硝基间苯二酚与乙醛在碱性介质中的直接反应以适中的8.2%的总产率生成四硝基C 1-间苯二酚[4]芳烃,其特征在于单晶X射线晶体学,1 H NMR光谱和电喷雾电离质谱(ESI-MS)。在溶液和固态下,该产品采用独特的,热稳定的和前所未有的rcct-boat构型。
