- Palladium-catalyzed ortho-alkenylation of aryl hydrogen phosphates using a new mono-phosphoric acid directing group
-
A highly efficient Pd-catalyzed ortho-alkenylation is reported using a mono-phosphoric acid-directing group for the first time. This phosphoric acid-directing group is successfully utilized for the synthesis of various alkenylated products and offers a new approach to transition-metal-catalyzed C-H activation.

- Synthesis, characterization and thermal studies of cresol based polyphosphate esters
-
Polyphosphate esters were synthesized from cresol phosphorodichloridates and dihydric phenols by interfacial polycondensation using a phase transfer catalyst. The polymers were characterized by IR, 1H and 31P NMR spectroscopy and GPC. The thermal stability of the polymers was determined by thermogravimetry.

- Syntheses and spectral characterization of 2-aryloxy - 5,5′- bis(bromomethyl)-1,3,2P-dioxaphosphorinane 2-oxides
-
2-Aryloxy-5,5′-bis(bromomethyl)-1,3,2-dioxaphosphorinane 2-oxides 3 have been synthesized by the reaction of 2,2′-bis(bromomethyl)-1,3- propanediol 1 with various arvlphosphorodichloridates 2a-h in the presence of triethylamine in dry tetrahydrofuran at room temperatuure. Their 1H, 13C, 31P NMR and mass spectral data are discussed.
