Isoelectronic Relationships in Cluster Chemistry: Nucleophilic Addition to a Vinylidene Ligandfluorescence counterstainnuclear counterstainimmunocytochemistrypropidium iodidecell cultureThe polarity of vinylidene ligands is reversed in going from mononuclear to polynuclear vinylidene complexes. The electrophilic center ...
The enthalpies for the addition of hydroxide anion to substituted phenylisocyanates have been calculated with MNDO. The results obtained correlate well with the rates of addition of 2-ethylhexanol to phenylisocyanates. This allows us to estimate the rates for nucleophilic addition within reasonable limi...

1)nucleophilic addition reaction亲核加成反应 1.Ab initio and DFT(B3LYP) calculations using the 6-31G~(**) basis set were employed to study the mechanism of the nucleophilic addition reaction between silyleneimine and water .采用量子化学从头算和密度泛函方法在HF/6-31G**及B3LYP/6-31G**水平上...
The systems MII-ONC(CN)2 −-L-MeOH-H2O [M = Ni, Cu, Co or Pd; L = pyrazole (pz)] were studied to determine conditions for the nucleophilic addition of MeOH to nitrosodicyanomethanide (ndcm)− in the metal coordination sphere. Compounds containing two or three bidentate anionic ch...
The various add adducts are the result of a two-step SEAr process of the addition-elimination type. Scheme 3 Open in figure viewerPowerPoint The graphs Ln (Ae − A) as a function of time measured for a given interaction are linear (R2 > 0.9998). From the slope of these ...
The mechanism of addition of selenium dihalides to vinyl ethers was studied at the B3LYP/6-311+G(d,p) level of theory. The reaction goes in two steps throu... EA Chirkina,KA Chernyshev,Pankrata??ev, E. Yu.,... - 《Russian Journal of Organic Chemistry》 被引量: 5发表: 2013年 Qu...
