Both DCNP (nerve gas Tabun mimic) and Cd2+ are extremely toxic to mankind. We have focused our research on quantitative estimation of DCNP and Cd2+ in given water samples. A carbazole-pyrrole conjugate CPC has been designed and synthesized which possesses a unique characteristic feature of detecting two hazardous analytes DCNP and Cd2+ by giving two different optical responses i.e. visual color changes and fluorescence "turn-on" respectively. The PET based chemosensor CPC produces a new compound CPC-1 and a highly fluorescent CPC-Cd2+ complex upon addition of DCNP and Cd2+, respectively. The detection limit of CPC for DCNP and Cd2+ has been estimated to be 7.75 nM and 0.27 μM, respectively, at pH 7.0. Quantum chemical calculations have been executed to demonstrate the electronic properties and the mechanism of the receptor-donor interactions. The concentrations of DCNP and Cd2+ ions in various water samples have been estimated with the help of standard absorbance and fluorescence curves.
A Novel Phase Transfer Catalyzed Synthesis of Dialkyl Phosphorocyanidates from Dialkyl Phosphorochloridates
Shi, Enxue,Pei, Chengxin
, p. 1285 - 1288 (2004)
Dialkyl phosphorocyanidates 2a-2d were prepared from dialkyl phosphorochloridates 1a-1d and potassium cyanide in high yield under phase transfer catalyzed conditions.
New route to O,O-diethyl phosphorocyanidate
Lopusinski, Andrzej
, p. 395 - 397 (2004)
A new and efficient route for synthesis of O, O-Diethyl Phosphorocyanidate by decomposition of diethyl phosphoryl-1,2,4,-dithiazolin-5-one was discussed. The use of phosphorocyanidates as coupling reagents in peptide chemistry and other applications of these compounds in organic synthesis was also demonstrated. It was found that these compounds were relatively unstable and could decompose easily, especially in the presence of water with the formation of hydrogen cyanide. A new efficient route to O, O-dialkyl phosphorocyamidates was offered, which were not contaminated by isomeric isocyanidates and could be used as the substrates for further synthetic purposes.
Radical cyanation of alkyl iodides with diethylphosphoryl cyanide
Chang, Ho Cho,Jin, Young Lee,Kim, Sunggak
body text, p. 81 - 84 (2009/05/30)
The β-elimination of an organophosphoryl group from an iminyl radical is observed for the first time. On the basis of this finding, radical cyanation of alkyl iodides is achieved by using diethylphosphoryl cyanide. Georg Thieme Verlag Stuttgart.
