Abstract :
Abstract -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 effect have
been effected on the bond length in 2- phosphinanes.
