The actual rearrangement reaction takes place when the amine group attacks the thiocarbonyl in a nucleophilic addition temporarily forming an aziridine and the thioacetamide by tautomerization.
32.
A monosaccharide can switch from the cyclic form, through a nucleophilic addition reaction between the carbonyl group and one of the hydroxyls of the same molecule.
33.
This mechanism involves a trimolecular reaction between the isocyanide ( R NC ), the carboxylic acid, and the carbonyl in a sequence of nucleophilic additions.
34.
The first step in the catalytic cycle reaction is the nucleophilic addition reaction of the oxone with the ketone group on the catalyst ( intermediate 1 ).
35.
Cram's rule predicts the majordiastereomer resulting from the "'diastereoselective "'nucleophilic addition to a carbonyl group next to a chiral center.
36.
The nucleophilic addition and the protonation of peptide amide nitrogen is a very fast process that is believed to occur as a single step in the catalytic process.
37.
A number of functional compounds with a variety of applications are available by nucleophilic addition at the activated double bond of the vinyl sulfonic acid and its derivatives.
38.
Nucleophilic addition of aminonitrile to CO 2 leads to cyano-carbamic acid, which undergoes an intramolecular ring closing to 5-imino-oxazolidin-2-one.
39.
The nucleophilic addition of urea gives the intermediate "'4 "', which quickly dehydrates to give the desired product "'5 " '.
40.
A hydroxide anion attacks one of the ketone groups in "'1 "'in a nucleophilic addition to the hydroxyl anion "'2 " '.
