Imine synthesis from amide
Imines participate in many reactions that are analogous to the reactions of aldehydes and ketones:. Wang, Synlett, 25 The corresponding amides were obtained in high yields, with good functional group compatibility. Williams, Org. Site Search any all words. From p. Water is eliminated in the reaction, which is acid-catalyzed and reversible in the same sense as acetal formation. N -Alkylidenesulfinamides".
A chemoselective activation of a secondary amide with triflic anhydride in the presence of 2-fluoropyridine enables a mild reduction using triethylsilane, a cheap.
Imines are usually made from carbonyl compounds and primary amines under acidic conditions. The number of carbon atoms in the aldehyde and the amide ( propionamide is the starting material) are the full synthesis.
or both, required in the synthesis of a given imine or enamine.

Secondary amides can be reduced by silane HSiMe2Ph into imines and aldehydes Synthesis.6 Catalytic hydrosilylation of tertiary amides to. An imine is a functional group or chemical compound containing a carbon– nitrogen double Several other methods exist for the synthesis of imines.

Reaction of organic azides with metal carbenoids (produced from diazocarbonyl compounds).
It should be noted that, like acetal formation, these are acid-catalyzed reversible reactions in which water is lost. Yang, Synlett, 27 Wang, L.
