Witryna30 lis 2001 · The kinetics of Z/E isomerization of these imines have been studied in glacial acetic acid (1Ea and 1Zc) and in dioxane solutions containing HCl, trifluoromethanesulfonic acid, or tetrafluoroboric acid (1Ea, 1Zb, 2Ea, and 2Zb). The isomerization takes place by either (a) rotation about the carbon-nitrogen double bond … WitrynaImines are typically prepared by the condensation of ammonia or primary amines with aldehydes and ketones. The mechanism of imine formation will be further discussed in Section 8.02.3.2.Although this method of imine formation is reversible requiring long reaction times and the use of acid catalysts and dehydrating agents such as …
WitrynaReaction with primary amines to form imines. The reaction of aldehydes and ketones with ammonia or 1º-amines forms imine derivatives, also known as Schiff bases (compounds having a C=N function). Water is eliminated in the reaction, which is acid-catalyzed and reversible in the same sense as acetal formation.
