Several new class of phosphorus heterocyclic compounds containing exocyclic P–C link such as 6-(2′-chloroethyl)/(allyl)/(benzyl)-1,2,4,8,10,11-hexachloro-12H-dibenzo[d,g][1,3,2]dioxaphosphocin 6-oxides (5—7), 2-(2″-chloroethyl)/(allyl)-6-(1,1-dimethylethyl)-3-cyclohexyl-3,4-dihdro-2H-1,3,2-benzoxazaphosphorin 2-oxides (9, 10), 2-(2″-chloroethyl-2,3-dihydro-3-(4′-bromophenyl)-1H-naphth[1,2-e][1,3,2]-oxazaphosphorin 2-oxide (12), 2-(2″-chloroethyl)/(allyl)-2,3-dihydro-5-benzoyl-1H-1,3,2-benzodiazaphosphole 2-oxides (14, 15), 4-phenyl-2-(2″-chloroethyl)-1H-1,3,3a,5,6-pentaza-2-phosphapentalene 2-oxide (17) and 4-benzyl-2-(2″-chloroethyl)-1H-1,3,3a,5,6-pentaza-2-phospha-pentalene 2-oxide (19) were synthesized by reacting equimolar quantities of corresponding diol (4)/diamines (13, 16, 18), 2-cyclohexylaminomethyl-4-t-butylphenol (8) and 1-(4′-bromoanilinomethyl)-2-naphthol (11), with respective phosponyl dichlorides (1—3) in dry toluene/toluene-tetrahydro-furan/pyridine in the presence of triethylamine at various temperatures. Their structures were established by IR, 1H-, 13C- and 31P-NMR spectral data. The mass spectral data were given for compounds 9, 12 and 15. The title compounds were screened for antibacterial activity against Staphylococcus aureus and Escherichia coli and antifungal activity on Aspergillus niger and Helminthosporium oryzae. Most of the compounds possess significant activity.
