Use:
PhHMDS is widely used in the field of organic chemistry, especially as a catalyst for strong alkali agents and silicon sources. It has the following main uses:
-Strong alkaline agent: PhHMDS can be used as a non-aqueous alkaline agent for deprotonation and alkaline reagents.
-Highly active metal silane reagents: PhHMDS can be reacted with metal halides to prepare highly active metal silane reagents, such as aluminum silane and zinc silane, catalysts for organic synthesis reactions.
-Deblocking agent: PhHMDS can be used for deblocking reactions in organic synthesis processes.
Preparation Method:
The preparation of PhHMDS is generally carried out by the following steps:
1. the reaction of hexyl aluminum bromide and phenyl red blue to generate 6-hexyl benzene.
2. 6-hexylbenzene reacts with dimethylchlorosilane to generate 6-hexyl-dimethylchlorosilane.
3. Finally, 6-hexyl-dimethylchlorosilane is reacted with dimethylaniline to produce PhHMDS.
Safety Information:
When using PhHMDS, you need to pay attention to the following safety precautions:
-Avoid contact with skin, eyes and respiratory tract. Wear gloves, goggles and a mask when using.
-Use in a well-ventilated place to avoid prolonged exposure indoors.
-Avoid contact with oxygen and moisture during storage to avoid dangerous reactions.
-If you have been exposed to PhHMDS, rinse immediately with plenty of water and seek medical help.
