Oxidative conversion of isothiocyanates to isocyanates by rat liver.
This report describes the oxidative metabolism of isothiocyanates to isocyanates catalyzed by rat liver microsomes. Incubation of 2-naphthylisothiocyanate, microsomes, and NADPH yielded either N,N'-di-naphthylurea or, on inclusion of 2-aminofluorene in the incubations, N-2-naphthyl-N'-2-fluorenylurea. These ureas were formed by the production of the known genotoxicant, 2-naphthylisocyanate, whi...
متن کاملA Rapid and Efficient Route to Preparation of Isocyanate Microcapsules
In this paper, polyaryl polymethylene isocyanates (PAPI) were used as an innovative alternative material to prepare isocyanate microcapsules. PAPI could be used as core materials, which would react with small molecules containing active hydrogen (1,4-butanediol, ethylene glycol, 1,2-diaminoethane etc.). The reaction products of PAPI and active hydrogen would form a shell by interfacial polymeri...
متن کاملCO2 conversion to isocyanate via multiple N-Si bond cleavage at a bulky uranium(III) complex.
The reaction of the sterically saturated uranium(III) tetrasilylamido complex [K(18c6)][U(N(SiMe3)2)4] with CO2 leads to CO2 insertion into the U-N bond affording the stable U(IV) isocyanate complex [K(18c6)][U(N(SiMe3)2)3(NCO)2]n that was crystallographically characterized. DFT studies indicate that the reaction involves the [2+2] cyclo-addition of a double bond of O=CO to the U-N(SiMe3)2 bond...
متن کاملQuantifying Internet End-to-End Route Similarity
Route similarity refers to the similarity of two routes between two nodes and an arbitrary third node. This intuitive concept plays an important role in distributed system deployment and path-edge inference. However, route similarity has not been quantitatively studied from an end-node perspective, and its properties are poorly understood. In this paper, we make an initial effort in quantifying...
