This makes the carbon less electrophilic which explains why esters are less reactive than ketones or aldehydes. Logged adultstudent Regular Member Posts: 9 Mole Snacks: +0/-0 Re: Why are esters less reactive than ketones? « Reply #2 on: April 28, 2012, 12:20:11 PM » Thanks ...
Oxidation of A2E Results in the Formation of Highly Reactive Aldehydes and Ketones 来自 Wiley 喜欢 0 阅读量: 27 作者:W Zhen,LMM Keller,J Dillon,ER Gaillard 摘要: It has been reported that the photo-oxidation of A2E, a component of human retinal lipofuscin, leads to products that are ...
Reactive extraction of carbonyl compounds (aldehydes, ketones) from hydrocarbon mixtures applying aqueous solutions of several amino and bisulfite salts was studied. Results obtained for hydrazone formation salts and sodium bisulfite show an increase of distribution ratio of benzaldehyde of up to 1000 ...
At the same time, our calculations revealed that XVIIsα was less reactive toward chlorination with Cu(II) complex I, as MECPsα is 9.4 kcal/mol higher in energy than MECP4a (Figs. 4 and 5). As such, in this case, the intrinsic stability of the radical species is not a determining ...

Reactive zinc metal can be prepared by the electrolysis of a DMF solution containing Et4NClO4 with a platinum cathode and a zinc anode. The reaction of 2-bromomethyl-1, 4-dibromo-2-butene (1) with aldehydes or ketones in the presence of the electrogenarated reactive zinc (EGZn) in DMF...

A Reformatsky-type aldol reaction of α-chloroketones with aldehydes has been achieved using reactive barium as a low-valent metal in THF; this one-pot process is more effective for obtaining the desired β-hydroxy ketones in high yields than the stepwise process in which barium enolates are ...
