In the N-substituted benzoyl-thio-urea, C(24)H(23)N(5)OS, the benzoyl-thio-urea unit is non-planar (r.m.s. deviation = 0.126 Å). The aliphatic part of the tetra-hydro-quinoline fused-ring system is disordered over two positions in a 0.592 (5):0.408 (5) ratio. The pyridine and pyrrole rings are twisted by 55.2 (1)° in order to avoid crowding of their respective substituents. Pairs of mol-ecules ...

Abstract. Furans are emitted to the atmosphere during biomass burning from pyrolysis of cellulose. They one major contributing volatile organic compound (VOC) classes OH and NO3 reactivity in plumes. The removal process furans at night is reaction with nitrate radical, NO3. Here, we report a series relative rate experiments 7300 L indoor simulation chamber Institut de Combustion Aérothermique R...

Reaction of Glycin with Malononitrile afforded respective Pyrrole. Pyrrole is one of the heterocyclic compounds with very important biological activities. Heterocycles are extremely important because of their wide range of applications that goes from their use as pharmaceuticals and agrochemicals to dyestuffs and additives. In this view, it was proposed to synthesize pyrrole-3-carbonitrile deri...

Abstract: Electrical sensitivity of a boron nitride nanotube (BNNT) was examined toward pyrrole (C5H6N) molecule by using density functional theory (DFT) calculations at the B3LYP/6-31G (d) level, and it was found that the adsorption energy (Ead) of pyrrole on the pristine nanotubes is a bout -16.37kcal/mol. But when nanotube have been doped with Si and Al atom...
