Amide as Nitrogen Source： Amination and Mechanism

Ammonium salts as an inexpensive and convenient nitrogen source in the Cu-catalyzed amination of aryl halides at room temperature.

Convenient and inexpensive ammonium salts such as NH(4)Cl and aqueous NH(3) solution are found to be readily utilized in the Cu-catalyzed room temperature N-arylation of aryl halides, providing N-unprotected aniline derivatives in high yields.

The Amide Nitrogen of Blood.

Certain chemical changes are known to occur in muscle during, and immediately following, short periods of exercise. With respect to the alteration in the acid-base equilibrium under such conditions, some facts are definitely established. It has been shown by Barr and Himwich (1) that within a few minutes after exercise very considerable, amounts of plasma bicarbonate are neutralized by acid, an...

Insects as a Nitrogen Source for Plants

Many plants have evolved adaptations in order to survive in low nitrogen environments. One of the best-known adaptations is that of plant symbiosis with nitrogen-fixing bacteria; this is the major route by which nitrogen is incorporated into plant biomass. A portion of this plant-associated nitrogen is then lost to insects through herbivory, and insects represent a nitrogen reservoir that is ge...

Iron-catalyzed direct amination of azoles using formamides or amines as nitrogen sources in air.

A new iron-catalyzed, direct C-H amination of azoles at C2 has been developed by using formamides or amines as nitrogen sources. Imidazole is the only additive in the catalyst system and oxygen in air is employed during the transformation process.
