124750-51-2 - Introduction
N-(Triphenylmethyl)-5-(4 '-bromomethylbiphenyl-2-yl) tetrazole, also known as Br-PhABZ or TBATB. Its chemical structure is as follows:
Nature:
1. Appearance: White crystalline solid.
2. Solubility: Soluble in a variety of organic solvents, such as dimethylformamide (DMF), dichloromethane (DCM), etc.
3. melting point: about 150 ℃ to 160 ℃.
Use:
1. Br-PhABZ is widely used in the field of organic synthesis, especially in tandem reactions (such as Suzuki coupling, Stille coupling, etc.).
2. As the ligand of the dual catalyst, Br-PhABZ can coordinate with transition metals to generate complexes with catalytic activity for asymmetric synthesis and other reactions.
3. Br-PhABZ can also be used as a raw material for high energy density materials and organic light-emitting diodes (OLED).
Method:
The synthesis of Br-PhABZ is generally divided into two steps:
1. First, in the presence of trityl alcohol, phenylmagnesium bromide and bibenzaldehyde are reacted to obtain 4 '-bromomethylbiphenyl-2-formaldehyde.
2. Next, 4 '-bromomethylbiphenyl-2-carbaldehyde and pentaphenylmethylated tetraaminopyrimidine are reacted under basic conditions to obtain N-(triphenylmethyl)-5-(4'-bromomethylbiphenyl-2-yl) tetrazole.
Safety Information: The toxicity and danger of Br-PhABZ are limited, but it is still necessary to pay attention to safe operation when used as a chemical.
2. contact with skin, eyes or body, should immediately rinse with plenty of water, and wash hands. If you feel unwell, you should seek medical help.
3. During storage and handling, avoid contact with oxidants and strong acids to prevent dangerous reactions.
4. in the indoor environment must be properly ventilated to avoid inhalation of its vapor or dust. For prolonged operation, wear personal protective equipment such as gloves, goggles and protective clothing.
