In this study,hybrid density functional theory[1] is used to study oxidation of methane to methanol mediated by the [CuⅡCuⅡ(μ-O)2CuⅢ(7-N-Etppz)]1+complex.[2] Based on the calculated free-energy profil
Allylmetal species are important intermediates in organic synthesis.[1] Recently, Stamatis E. Korkis and co-workers[2] first reported allyl-to-allyl 1,4-Rh(Ⅲ) migration in the oxidative C-H allylation
Transition-metal catalyzed C-H bond functionalization have emerged as a powerful synthetic method and been extensively reported.[1] Recently,Chatani et al [2]reported the rhodium-catalyzed reaction of
The isoquinolones have caused widespread concern because of its specific structural motifs [1].The method of the transition metal catalyzed C-H functionalization has become quite perfect and use this
Organic fluorine compounds such as freon,fluoro-liquid crystals,optical fiber,poly(tetrafluroethylene)(PTFE),pharmaceuticals and agrochemicals etc.,have received great interest and attention in divers
Polyfluorenes(PFs)are widely used as blue-light-emitting materials in polymer light-emitting diodes(PLEDs)because of their high pholuminescence yields,high hole mobility and thermal stability.
The hydrogen bonding interactions in a series of glycolic acid-small molecule complexes were studied by the generalized Kohn-Sham energy decomposition analysis(GKS-EDA).
The ab initio valence bond(VB)methods is applied to study the mechanism of the reaction of alkalis and halogen.The crossing and coupling matrix of two covalent and ionic nonadiabatic states are obtain
In this work,a hierarchy of valence bond(VB)methods is proposed by using the concept of seniority number,which is defined as the number of singly occupied orbitals in a determinant or an orbital confi
