Both, 3,4-dimethylpyrazole phosphate (DMPP) and N-(n-butyl) thiophosphoric triamide (NBPT) are commonly used as nitrogen (N) stabilizers, often in agriculture to reduce loss from soils by inhibiting soil nitrification slowing down urea hydrolysis, respectively. The current knowledge gap concerns how microbial communities involved N cycling affected the long-term use of DMPP NBPT. present field ...

tetra-n-butyl ammonium hydroxide was used as a catalyst for one-pot, three component condensation reactions consisting of aromatic aldehydes, malononitrile and barbituric acid in ethanol:water solvent system at 60oc. current method has major advantages like mild reaction conditions with simple operation, high yields, by using a less toxic and lower costlier catalyst.in conclusion, we have explo...

the composite diazotization coupling reaction of sulfanilic acid and n, ndimethylaniline was used for the precise, accurate, and rapid determination of trace amounts of nitrite ion (0.02-3 µg/ml). the reaction was monitored spectrophotometrically by measuring the absorbance of the produced methyl orange at 510 nm by a fixed the method of 5.0 minutes. the relative standard deviation for the dete...

In the title benzamide derivative, C(11)H(14)ClNO, the chloro-benzene and butyl-amine groups are each planar, with mean deviations from the planes of 0.013 and 0.030 Å, respectively, and a dihedral angle of 2.54 (9)° between the two planes. In the crystal structure, N-H⋯O hydrogen bonds link mol-ecules in rows along a. Short inter-molecular Cl⋯Cl inter-actions [3.4225 (5) Å] link these rows int...

A simple and practical method has been developed for the regioselective nitrosylation of imidazopyridines via C(sp(2))-H bond functionalization using tert-butyl nitrite under mild reaction conditions in a short time. A library of 3-nitrosoimidazopyridines with broad functionalities was synthesized in near quantitative yields. The present protocol is also applicable to imidazo[2,1-b]thiazole and...

A new method for the synthesis of allyl aromatic compounds not involving any metal-containing reagent or catalyst has been developed. Arylamines substituted with a large number of different substituents were converted via diazotizative deamination with tert-butyl nitrite in allyl bromide and acetonitrile to the corresponding allyl aromatic compounds. The allylation reaction was found to be suit...

nitrite is responsible for some characteristics of cured meat products such as color, flavor and suppressing the outgrowth and production of toxin from clostridium botulinum. despite all of its desired properties, nitrite is responsible for the formation of carcinogenic n-nitrosamine. in this study, nitrite-free and low-nitrite meat curing systems were developed to eliminate or reduce nitrite f...
