| Abstract: | Abstract A series of 2-alkyl-2-oxo-1,2,3-dioxaphosphorinane (1) and some 2-alkyl-2-oxo-1,2,3-dioxaphosphepane (II) were synthesized and their NMR, IR as well as MS were reported. The substituent effect on 31P chemical shifts and conformations of these compounds were investigated by the molecule, mechanics calculations using Allinger's MM2 program. |
