The ferrous form of sulfmyoglobin was isolated as the first stable product of the reaction of a single mole of inorganic sulfide with 1 mole of the higher oxidation state derivative of myoglobin, Mb’“. Using radioactive sulfide, it was demonstrated that a single g atom of sulfur is incorporated per mole of myoglobin to form sulfmyoglobin. More than 85% of the radioactive sulfur is extracted int...

reaction of substituted-aniline (8) with ethyl (l-methyl-5-nitroimidazole-2- carbonyl) acetate (9) gave 4-hydroxy-2-(l-methyl-5-nitro-2-imidazolyl)- substituted-quinolines (lo), which were converted to compound 11 with phosphorus oxychloride. substituted-2-(l-methyl-5-nitro-2-imidazo1yl)-4.- methyl-(or phenyl-) quinolines (14) were prepared through the reaction of 2- acetyl-5-nitro-1-methyl-imi...

Graphical Abstract “My favorite thing about my lab group is how funny they are (aside from being fantastic and creative chemists, that is)! The memes on our twitter page not doing … My name reaction the Beckmann Rearrangement. Single-atom skeletal editing traces back to carbonyl rearrangements, you can't beat a gave us Azithromycin Nylon …” Find out more Mark Levin in his Introducing Profile.

The detailed hydration mechanism of carbonyl sulfide (COS) in the presence of up to five water molecules has been investigated at the level of HF and MP2 with the basis set of 6-311++G(d, p). The nucleophilic addition of water molecule occurs in a concerted way across the C==S bond of COS rather than across the C==O bond. This preferential reaction mechanism could be rationalized in terms of Fu...

the wittig reaction rate can be dramatically enhanced by irradiation of the reaction mixture containing an aldehyde or ketone; methoxymethyl(triphenyl)phosphonium chloride, potassium t-butoxide, and t buoh with a commercial microwave oven. carbonyl compound are converted to witting products within three min. in good yields.

photocatalytic reduction of carbon dioxide to formaldehyde was investigated on four semiconductor photocatalysts (fes, fes/fes2, nio and tio2). the reaction was carried out in continues flow of co2 gas bubbled into the reactor. semiconductor photocatalysts were characterized by x-ray diffraction (xrd) and diffuse reflectance spectroscopic (drs) methods. sulfide ion was used as hole scavenger. t...
