Sulfuric Acid → HCID 1627481, compound

Participants

Reaction Steps

A mixture of 18.0 gms. pentachlorobenzonitrile and 200 ml concentrated sulfuric acid (97 weight % H2SO4) was heated to 145° C. over a period of approximately 40 min. Complete dissolution of the pentachlorobenzonitrile was observed to occur at 130° C. thereby giving a pale straw solution. When cool, the reaction mixture was poured onto ice and the white solid thereby formed was isolated by filtration. In this manner there was formed 18.0 gms. (94% yield) pentachlorobenzamide. Identity of the product was established with the aid of both analytical and spectral data.
