Theoretical studies on C-heteroatom bond formation via reductive elimination from group 10 M(PH3)2(CH3)(X) species (X = CH3, NH2, OH, SH) and the determina... Both direct reaction from the four-coordinate species and a three-coordinate mechanism involving initial PH3 loss have been consi...
A series of anionic boron compounds, possessing a polarized boron–metal bond, were synthesized and structurally characterized. Detailed analyses of these ... M. Yamashita - ChemInform 被引量: 0发表: 2011年 ChemInform Abstract: ACTIVATION ENERGIES IN NUCLEOPHILIC DISPLACEMENT REACTIONS MEASURED AT 296...
There are two formula units in the asym- metric unit. Each of the two crystallographicaUy independent Zn atoms is five-coordinate, is chelated by two glycinate molecules, and forms a fifth bond to a carboxyl O atom in a neighbouring bis(glycinato)- zinc complex. The coordination is ...
According to our results (Supplementary Fig. 3), there is no classical two-centre–two-electron (2c–2e) C–Be bond in Be5C2 monolayer. For one unit cell of Be5C2 monolayer, the SSAdNDP search revealed twenty-four 3c–2e Be–C–Be s-bonds (responsible for the bonding within the ...
According to the internal rotation of two hydroxyl groups around the C–B bond, four conformers are suggested: TC, CT, TT, and CC (C/T refer to the cis/trans positions of O10-H15 and O9-H14 groups towards the C–B bond). The results of calculations favor the TC conformer with a...
In both complexes 5 and 6 the title ylide is coordinated through the ylidic carbon and the phosphine atom. However, in compound 6 the Hg鈥揅 bond length is considerably weakened due to coordination of DMSO molecule to the metal ion and locating of ylidic carbon atom in the axial position ...
