benzylidene aniline synthesis

The amines are more soluble in acid chloride than in NaOH, the reaction occurs preferably between benzoyl chloride and amine. Dry the product and calculate the percentage yield.3. After 30 minutes we obtained pyrano quinolines 3a and 4a in a ratio of41:59 in an overall yield of 80 % (Scheme 1). THERMOLYSIS OF α-( Use: VIII. VI. Principle: Insertion of benzoyl moiety instead of an active hydrogen atom present in hydroxyl (OH) primary amino (NH2) or secondary amino group (NH) is usually termed as benzoylation reaction.1 This particular reaction essentially bears a close resemblance to the phenomenon of acetylation except that in this specific instance the reagent is (benzoyl chloride) which reacts in the presence pyridine or 10% NaOH and not benzoic anhydride. A simple photocatalytic method was developed for the synthesis of unsymmetrical 1,2-diamines by the unprecedented reductive coupling of N-benzylidene-[1,1'-biphenyl]-2-amines with an aliphatic amine.The presence of a phenyl substituent in the aniline moiety of the substrate was critical for the reactivity. -ARYL)BENZYL ARYL SULFIDES.
