标题:O-Acylbenzonitriles: Synthesis And Heterocyclization Under Acid Hydrolysis Of The Cyano Group
摘要:2-Cyanobenzophenones Were Synthesized By Reaction Of 2-Bromobenzophenones With Copper(I) Cyanide In Dmf,And Their Transformations Involving Acid Hydrolysis Of The Cyano Group Were Studied. Reactions Of O-Benzoylbenzonitriles With Trifluoroacetic Acid In The Presence Or In The Absence Of Sulfuric Acid Afforded 3-Hydroxyphthalimidines In High Yields. Under Analogous Conditions,Benzonitriles Having No Acyl Group In The Ortho Position Were Converted To The Corresponding Benzamides. 2-Cyanobenzophenones Reacted With Sulfuric Acid In The Absence Of Trifluoroacetic Acid To Give Only Substituted Anthraquinones.
