用(U)B3LYP和(U)MP2方法在6-311++G(d
p)水平上计算了含硼、氮和呋喃氧五元高能量材料优化构型、芳香性、生成焓、燃烧热、质子与负氢离子亲和势
得到了势能面上10个稳定的五元环化合物.所得到的五元环化合物均有较大的NICS值
表明这些化合物具有较强的芳香性.作为高能材料
生成焓和燃烧热分别在37.7~134.8kJ/mol和10~31kJ/g范围内
均接近于三元硼氮高能材料的相应值.负氢离子亲和势比质子亲和势低
表明含硼、氮和呋喃氧五元化合物显碱性.
Using the(U)B3LYP and(U)MP2 methods with the 6-311++G(d
p) basis sets
it is calculated that geometries
aromaticity
enthalpies of formation and combustion
and the proton and hydride affinities for the predicted five-membered rings high energy-density materials B2N2OHp(p=0
2
) which contain boron
nitrogen and furanoxo groups.Only ten possible compounds were obtained as minima at the potential energy surfaces.All of the five-membered rings compounds have large negative NICS values and the great aromatic properties.As the high energy-density materials
the enthalpies of formation and the combustion energies are 37.7 to 134.8 kJ/mol and 10 to 31 kJ/g
respectively
which is fairly close to those of the three-membered boron-nitrogen HE materials.The hydride affinities are lower than the proton affinities
indicating that the Lewis acidity of the five-membered rings compounds containing oxygen
boron and nitrogen
would be dwarfed by the Lewis basicity.
