In the present work we investigated a novel triplet ground-state germylenoid HB=GeLiF as well as its insertion reactions with RH(R = F,OH and NH2) using the DFT B3LYP and QCISD methods for the first time.Geometry optimization calculations show that the triplet HB=GeLiF has three equilibrium structures,in which the four-membered ring structure is the most stable with the lowest energy.All mechanisms of the three insertion reactions of germylenoid HB=GeLiF with RH(R = F,OH,and NH2) are identical to each other.Based on the calculated results,it is concluded that under the same conditions the insertion reactions should occur easily in the order of H-F > H-OH > H-NH2.In THF solvent the insertion reactions get more difficult than in the gas phase. 相似文献

关于亏函数的亏量和F.Nevanlinna猜想 总被引:2,自引:0,他引:2
在亚纯函数值分布论的发展中,有一个有名的 F.Nevanlinna猜想.即:若f(z)是有限级λ的亚纯函数,且∑δ(a,f)=2(a是f的亏值),则 (i)λ是1/2的整数倍; (ii)v(f)≤2λ,其中v(f)是f的亏值个数; (iii)亏量δ(a,f)是1/λ的整数倍. 相似文献
