Aromatic and single-olefin six-membered BN heterocycles were synthesized, and the heats of hydrogenation were measured calorimetrically. A comparison of the hydrogenation enthalpies of these compounds revealed that 1,2-azaborines have a resonance stabilization energy of 16.6 ± 1.3 kcal/mol, in good agreement with calculated values.
芳香族和单烯烃六元 BN 杂环被合成出来，并通过量热法测量了它们的氢化热。对这些化合物氢化焓的比较表明，1,2-氮杂硼杂环具有 16.6 ± 1.3 kcal/mol 的共振稳定能，与计算值吻合较好。
