چکیده

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.
