Synthesis of Carbamoyl Fluorides Using a Difluorophosgene Surrogate Derived from Difluorocarbene and Pyridine N-Oxides was written by Cadwallader, Dusty;Tiburcio, Tristan R.;Cieszynski, George A.;Le, Christine M.. And the article was included in Journal of Organic Chemistry in 2022.Name: 4-(Benzylamino)benzonitrile This article mentions the following:
The authors report a method for the synthesis of carbamoyl fluorides from secondary amines using bench-stable, inexpensive, and readily accessible starting materials that, when combined, yield a surrogate for toxic difluorophosgene (COF2) gas. In contrast to state-of-the-art methods for the synthesis of carbamoyl fluorides, the current protocol does not require the use of pre-functionalized substrates, the preparation of light-, temperature-, and/or moisture-sensitive chems., nor the application of explosive fluorinating reagents. In the experiment, the researchers used many compounds, for example, 4-(Benzylamino)benzonitrile (cas: 10282-32-3Name: 4-(Benzylamino)benzonitrile).
4-(Benzylamino)benzonitrile (cas: 10282-32-3) belongs to nitriles. Nitrile compounds can be prepared by the incorporation of a cyanide source through C–C bond formation or by dehydration of primary carboxamides. In addition, Nitriles can react with alkynes, which leads to an increase in carbon chain length (carbocyanation).Name: 4-(Benzylamino)benzonitrile
