Nis reaction mechanism
WebbHere is the mechanism of this reaction: The mechanism for iodination is slightly different: iodine (I 2) is treated with an oxidizing agent such as nitric acid to obtain the electrophilic iodine ("I + ", probably IONO 2 ). Other conditions for iodination include I 2, HIO 3, H 2 SO 4, and N -iodosuccinimide, H 2 SO 4.

Webb15 juli 2024 · The mechanism of N 2 fixation is as follows [5], [6], [7], [8]: N 2 absorbs onto the surface of the semiconductor. In the presence of light shining on the semiconductor, the photogenerated electron is transferred to the N 2 molecules. The sturdy triple bonds are weakened so that N 2 can be reduced, with the participation of water molecules.
