173035-11-5 - Introduction
1,3-Bis(2,4,6-trimethylphenyl)-4, (abbreviated as IMes) is an organic compound that belongs to a representative group of N-heterocyclic carbenes (N-Heterocyclic Carbene).
IMes has the following main properties:
-Appearance: Colorless or light yellow solid
-Melting point: 170-173°C
-Solubility: Soluble in organic solvents such as dichloromethane, toluene, ethanol, etc
IMes has a wide range of applications:
-Catalyst: IMes is commonly used as a ligand in metal catalysts and is widely used in organic synthesis reactions such as cross-coupling, asymmetric catalysis and inert bond activation.
-Organic synthesis: IMes reacts with acid or base to form active phosphites, which can be used for C- C bond formation reactions or the synthesis of transition metal complexes.
-Materials Chemistry: IMes and its derivatives are also used in the synthesis of polymer materials, metal-organic frameworks (MOFs) and electronic materials.
The preparation method of IMes is generally through the following steps:
1. dimethyl sulfoxide reacts with 2,4, 6-trimethylphenyl nitro compound to generate a product containing an imine group.
2. After reduction, deoxygenation and de-gas treatment, the relatively pure product of IMes was prepared.
Security information about IMes:
IMes is a relatively stable compound with no special risk. However, as with any organic chemical agent, it is recommended to take appropriate protective measures, such as wearing protective gloves and goggles, to avoid contact with skin and eyes. In addition, it should be operated in a well-ventilated laboratory environment to avoid inhalation of its dust and vapors.
