Usage

General Description

ALPHA,ALPHA,ALPHA'ALPHA'-TETRAMETHYL-1,3-BENZENEDIPROPIONITRILE, also known as BHT-CN, is a chemical compound commonly used as a stabilizer and antioxidant in a variety of products. It is a white, crystalline powder that is insoluble in water but soluble in organic solvents. BHT-CN is often added to plastics, rubbers, adhesives, and oils to prevent degradation from heat, light, and oxygen exposure. It is also used in food packaging, cosmetics, and personal care products to extend their shelf life and maintain their quality. BHT-CN has been deemed safe for use in these applications by regulatory agencies; however, care should be taken to handle it properly due to its potential for skin and eye irritation.

Expanding the scope of C-H amination through catalyst design

Analysis of the mechanism for Rh-mediated C-H amination has led to the development of a remarkably effective dinuclear Rh catalyst derived from 1,3-benzenedipropionic acid. This unique complex, Rh2(esp)2, is capable of promoting both

Observation of a Photogenerated Rh2 Nitrenoid Intermediate in C-H Amination

Rh2-catalyzed C-H amination is a powerful method for nitrogenating organic molecules. While Rh2 nitrenoids are often invoked as reactive intermediates in these reactions, the exquisite reactivity and fleeting lifetime of these species has precluded their observation. Here, we report the photogeneration of a transient Rh2 nitrenoid that participates in C-H amination. The developed approach to Rh2 nitrenoids, based on photochemical cleavage of N-Cl bonds in N-chloroamido ligands, has enabled characterization of a reactive Rh2 nitrenoid by mass spectrometry and transient absorption spectroscopy. We anticipate that photogeneration of metal nitrenoids will contribute to the development of C-H amination catalysis by providing tools to directly study the structures of these critical intermediates.
