Related Products of 86-29-3, Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. 86-29-3, Name is 2,2-Diphenylacetonitrile, SMILES is N#CC(C1=CC=CC=C1)C2=CC=CC=C2, belongs to benzodioxans compound. In a article, author is Ali, HM, introduce new discover of the category.

The inhibitory effects of a recently introduced series of the titled compounds on insect and mammalian acetylcholinesterase (AChE) activity were examined, where the median inhibition concentration (I-50) and the inhibition kinetic parameters, bimolecular inhibition rate constant (k(i)), affinity constant (K-a), and phosphorylation rate constant (k(p)), were determined for each compound. Results indicated that all examined dioxaphospholenes had less inhibitory effects on mammalian AChE than fenitrothion, a commercial pesticide with moderate mammalian toxicity. The highest selectivity was obtained with compounds containing glutamic and leucine moieties (2.70 and 2.18, respectively) while selectivity of fenitrothion was 0.93. The low inhibitory effects of the examined dioxaphospholenes on mammalian AChE were attributed to their low phosphorylation rates(k(p) < 2.2 min(-1)) compared to that of fenitrothion (k(p) = 4.84 min(-1)). QSAR equations indicated that the inhibition process is controlled mainly by both the phosphorylation rate (direct effect) and the affinity of compounds toward the enzyme (inverse effect). Although the compounds' hydrophobicity had no effects on the inhibition process, it affects the compounds' toxicity since it affects the ability of compounds to penetrate insects to reach the enzyme active site.

The present paper describes the ring-opening-closing alternating copolymerization of cyclic phosphonites (2-phenyl-1,3,2-dioxaphospholane (1a), 2-phenyl-1,3,2-dioxaphosphorinane(1b), 2-phenyl-1,3,2-dioxaphosphepane(1c), and 2-phenyl-4H-1,3,2-benzodioxa phosphorin-4-one(1d) with muconic acid(2a), succinaldehyde(2b), glutaraldehyde(2c), adipinaldehyde(2d), o-phthalaldehyde(2e), acrylic anhydride(2f), methacrylic anhydride(2g), N-methyl diacrylamide(2h), and N-methyldimethacrylamide(2i). The reaction of a 1:1 monomer feed ratio, explained by a mechanism of propagation via zwitterion intermediates, proceeds without any added catalyst to give an alternating copolymer 3 involving ring-opening of 1 and ring-closing of 2. The structure of copolymer 3 was determined by H-1, C-13 NMR, P-31 NMR and IR spectroscopies as well as elemental analysis.

Thermochemical conversion processes such as supercritical fluid extraction are used for producing biofuels from biomass. Supercritical fluid extraction process is decomposition process of lignocellulose or other organic materials thermally under supercritical conditions at 250-400 C temperature range under high pressure (4-5 MPa). In this study, the supercritical fluid extraction was used to produce bio-oils from algae. Supercritical fluid extraction trials were performed in a cylindrical reactor (75 mL) in organic solvents (acetone, ethanol and isopropanol) under supercritical conditions with (ferric chloride, potassium hydroxide) and without catalyst at the temperatures of 255, 275 and 295 C. The effects of process variables including temperature and catalyst on product yields were investigated. The produced liquids at 295 C in supercritical liquefaction were analyzed and characterized by elemental, GC-MS and FT-IR. 160, 122 and 108 different types of compounds were identified by GC-MS obtained in acetone, ethanol and isopropanol respectively. Bio-oils from supercritical liquefaction were composed of various organics including aromatics, nitrogenated and oxygenated compounds. Bio-oils obtained from supercritical liquefaction were found to have higher calorific values and superior fuel properties compared to feedstock.
