Abstract: Synthesis and spectral analysis of compounds 3-8 have been described. The synthesis of 2-substituted-5-methyl-2,3-dihydro-1,3,2λ5- benzoxazaphosphol-2-ones has been accomplished in a two-step process. In the first step 4-methyl-2-aminophenol is condensed with phosphoryl chloride in benzene in presence of TEA. The intermediate formed in this step is treated with various phenols and aromatic amines to afford the final products. The structure of these compounds is confirmed from analytical and spectral data (IR, 1H, 13C, 31P NMR and mass).
