- Lead ion induced chemodosimeter approach of a tripodal hydroxyl-quinoline based phospho-ester through P-O bond cleavage
-
Lead ion induced P-O bond breaking with instant colour change was observed in a tripodal hydroxyl-quinoline based phosphor-ester (HQP). A new penta-coordinated lead chelate complex [Pb4HQ6(ClO4)2] was found. The hydrolysis reaction followed by P-O bond cleavage with 'Pb-O' and 'Pb-N' bond formation proved the chemodosimeter approach.

- Nickel-catalyzed amination of aryl phosphates through cleaving aryl C-O bonds
-
The amination of triaryl phosphates was achieved using a Ni(II)-(σ-Aryl) complex/NHC catalyst system in dioxane at 110 °C in the presence of NaH as base. Electron-neutral, -rich, and -deficient triaryl phosphates were coupled with a wider range of amine partners including cyclic and acyclic secondary amines, aliphatic primary amines, and anilines in good to excellent yields.

- PHOTOCHEMICAL REACTIONS OF TRI-1-NAPHTHYL AND TRIS(8-QUINOLYL) PHOSPHATES
-
Upon UV-irradiation in alcohol, tri-1-naphthyl phosphate give 1-naphthyl 1,2'-binaphthalene-1'-yl phosphate and 1,1'-binaphthalene through intramolecular processes.Under the same conditions, tris(8-quinolyl) phosphate give alkyl phosphates by photo-alcoholysis, but in acetonitrile furadiquinoline was given.The reaction mechanisms was investigated by means of quenching experiments for fluorescence spectra and products by oxygen. - Key words: Tri-1-naphthyl phosphate; tris(8-quinolyl) phosphate; reaction mechanism; fluorescence spectra; UV spectra

- Polymer supported reagents: An efficiant and simple method for the synthesis of triaryl phosphates
-
The reaction of phosphoryl chloride with insoluble polymer-supported phenoxide ion reagents in benzene at room temperature, produced triaryl phosphates in excellent yields. The isolation of pure products by simple filtration and evaporation is an important feature of this method.

- FACTORS DETERMINING THE REACTIVITY OF PHOSPHOROUS TRIESTERS IN REACTIONS WITH CUMENE HYDROPEROXIDE
-
The kinetics of reduction of cumene hydroperoxide with a wide range of aliphatic and aromatic phosphorous triesters in benzene were studied by the polarographic method.Factors determining the reactivity of the phosphites in this reaction were investigated by the method of correlation analysis.
