Application of 5264-35-7, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 5264-35-7, molcular formula is C5H9NO, introducing its new discovery.
The Effect of Ring Size on Tetrahedral Displacement Reactions of Cyclic Imidates. Synthesis of O-(Fluoroalkyl)lactims and Higher O-Alkyllactims from Lower O-Alkyllactims
A recently developed synthesis of 2-(perfluoroalkyl)ethanols (RFCH2CH2OH) is based on heating 2-(perfluoroalkyl)-1-iodoethanes RFCH2CH2I with an amide, e.g., N-methylformamide or a lactam, 2-pyrrolidinone.The presumed O-<2-(perfluoroalkyl)ethyl>lactim intermediates have now been prepared in good to excellent yields (60-90percent) by heating a lower molecular mass O-alkyllactim with a higher-boiling alcohol, e.g., with RFCH2CH2OH, to displace the lower boiling alcohol.Competitive rate experiments showed that a 7-membered O-methyllactim reacted four to five times faster than did the 5-membered O-methyllactim.This difference is attributed to increased eclipsing strain, commonly called “I-strain”.In a “planar” 5-membered lactim ring, the engendered eclipsing strain appears to be greater than in the more flexible 7-membered ring.Reactant ratio and reaction conditions also affected the yield of lactim ether.Preparatively, reaction of C6F13CH2CH2OH (3) with O-ethylbutyrolactim (6) gave O-<2-(perfluorohexyl)ethyl>butyrolactim (7) in an 89.2percent yield (on unrecovered 3) at 67.9percent conversion.Yield was limited by dealkylation and condensation reactions that occurred during long heating times.By contrast, alcohol 3 with O-methylcaprolactim (10) gave 7-membered O-<2-(F-hexyl)ethyl>caprolactim (11) in 98percent yield at 90percent conversion.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 5264-35-7 is helpful to your research. Application of 5264-35-7
