Ester (organic compound) A compound most often formed by the condensation of an alcohol and an acid, with elimination of water, which contains the functional group carbon-oxygen double bond (i.e., carbonyl) joined via carbon to another oxygen atom. Ether A volatile, highly flammable liquid, ...

312 The tyrosine analog (67) (as its methyl ester) Co(saltyr)2 oxidizes benzylic substrates to their ketone.313 The requirement of an aliphatic aldehyde or ketone in these processes is such that an active CoIII-superoxo species (identified in EPR experiments) is formed.314 Electrochemic...

Can a benzyl ether be removed in the presence of an ester? I'd like to deprotect a benzyl group for a Fráter–Seebach alkylation. Would it be possible to do this with a Birch reduction using Li/NH3 (or Na/NH3), without also reducing the ester carbonyl group?..13...

it form salts with strong acids and addition complexes with Lewis acids. The complex between diethyl ether and boron trifluoride is an example. Ethers may react violently with strong oxidizing agents. In other reactions, which typically involve the breaking of the carbon-oxygen bond, ethers are re...
ester of chlorosulfonic acid, the trimethylsilyl chlorosulfonate (Cl-SO3-Si(CH3)3) (Figure 4) results in a decrease in the reaction rate, but (1) because of the ester function, no precipitation occurs throughout sulfonation and (2) chain scissions can be avoided, provided the reaction is ...
As it was shown in our previous work it is due to the shift of electron density form neighbouring bonds towards the CO group to cover the deficit in the negative charge created on this group due to the formation of a hydrogen bond with water (oxygen of carbonyl group plays here an ...
The various units are typically distributed statistically (i.e. also joined in a sequence other than that shown above). The phenol unit can also have a para bond to some extent. Here, R1is in each case independent hydrogen (in particular of m and n) or a phenolic C1-C26 alkyl substitu...
