These factors also focused on the ethanol sensing effects of the sensors on the acetaldehyde and ethyl methyl ketone tautomerism at room temperature, which have been formed within alcohol dehydrogenation and condensation reactions involved in chain growth pathways on SWNT. 展开 ...
PD Maria,A Fontana,G Cerichelli 摘要: The equilibrium constant for keto–enol tautomerism of 2-phenylacetylthiophene (2PAT) KT = [enol]/[ketone] has been determined as 3.55 × 10–7 (pKT 6.45) by combining rate constants for enolisation and ketonisation. The pKaKH for ionisation of 2...
11. Revisiting An “Un-Ketone-Like” Reaction With Br2 After all we’ve explored, I think we’re ready to go back at this “weird” reaction of a ketone one more time. How might this reaction work? We’re adding acid and forming a new bond to an electrophile at the alpha carbon. ...
The enol 2, produced by a Norrish type II photoelimination from 1, is protonated enantioselectively to ketone 3 in the presence of (–)-ephedrine. Best optical yields are obtained at 0oC using small amounts of the chiral amino... F Henin,J Muzart,JP Pete,... - 《Angewandte Chemie ...
The International Union of Pure and Applied Chemistry (IUPAC) name of a ketone is derived by selecting as the parent the longest chain of carbon atoms that contains the carbonyl group. The parent chain is numbered from the end that gives the carbonyl carbon the smaller number. The suffix -e...
An organic compound with a hydroxide group adjacent to a double bond; varies with a ketone form in the effect known as enol-keto tautomerism; an example is the compound CH3COH=CHCO2C2H5. McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyright © 2003 by The McGraw-Hill Comp...
For three enol-ketone pairs, equilibration of the thermodynamically disfavored tautomer was attempted with acids and bases but could not be effected, indicating kinetic inhibition of proton transfer. 机译:Breslow中间体(最早假设于1958年)是卡宾催化的油毡中的关键中间体。尝试分离和表征这些短暂的氨基烯醇...
