摘要
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.
