A CONVENIENT AND NOVEL ONE-POT SYNTHESIS OF 3-OXO-P-1,5,3-DIAZAPHOSPHEPINES AND 3-THIOXO-P-1,5,3-DIAZAPHOSPHEPINES

In a convenient one-pot sequence, treatment of benzil-dibenzylimine with sodium in dry tetrahydrofuran followed by addition of phosphorodichloridate and phosphorothiodichloridate yields 3-oxo-P-1,5,3-diazaphosphepines and 3-thioxo-P-1,5,3-diazaphosphepines, respectively. Key Words: Benzyl dibenzylimine; phosphorodichloridate; phosphorothiodichloridate; diazaphosphepines; spectral studies.
