[ 1 ] - Internal strain on the bond length and rate of hydrolysis in cyclic amides
The internal strain in cyclic amides are explained as a factor of resonance that are effected on the bond length C-N and are a major factor of rates of hydrolysis. The cyclic amides in this study are optimized by Gaussian program and the bond length of C-N in the rings are studied by HF/6-31G*.
[ 2 ] - Theoretical study of conformational properties and the anomeric effect study of the 2- phosphinanes
Ab initio HF/6-31G* Methode was employed to calculate the bond length in 2- phosphinanes when electronegative groups was at C-2 tend axial and equatorial positions. The magnitude of the anomeric effect depends on the nature of the substituent, the effect of the substituent can be seen by comparing the bond length in 2-chloro and 2-boromo substituented phosphinanes. The effect of anomeric eff...
[ 3 ] - Functionalization of Carboxylated Multi-Walled Nanotubes with Stabilised Phosphorus Ylide
In this paper, the chemical Functionalization of Carboxylate multi-walled carbon nanotubes by methyl (triphenyl phosphoranylidene) acetate have been investigated. Phosphorus Ylides are important compound in organic chemistry. At first, methyl (triphenyl phosphoranylidene) acetate, synthesized from salt metod in two steps: the formation of the phosphonium salt and the deprotonation of the latter...
