摘 要:以四唑衍生物和多取代基立方烷为例,评介了通过合理选择参照物、将设计等键等电子对反应简便地用于有机共轭和笼状体系的精确生成热的计算方法。还以实例指出以"基团加和法"求生成热的局限性。<Abstrcat> The calculation method of the accurate heats of formation for conjugated and cage systems has been reviewed, by choosing suitable reference compound and designing isodesmic reaction and taking examples of tetrazole derivatives and polysubstitut cubanes (i.e.the tetrazole and the cubane cage skeleton is not broken). It is pointed that the application of the group addition method to calculate the heats of formation is restricted in some case, for example, to calculate the heats of formation for polynitrocubanes.
