Abstract
The reaction of chiral and achiral salen ditopic ligands with sodium in dry isopropanol generates remote O,O-dianions. The dianions thus generated in situ are trapped by suitable phosphorus dielectrophiles to yield 2-oxo and 2-thioxo-1,3,7-dioxazaphosphadecines and 2-oxo and 2-thioxo-1,3,7,10-dioxadiazaphosphatridecines in moderate to good overall yield. The products are characterized by elemental and spectral (IR, 1 H, 13 C, 31 P NMR and Mass) studies. A plausible mechanistic logic and concept utilized in the synthesis have been discussed
