(E)-A-苯乙烯二硼酸二频纳酯 - Introduction
CIS-1,2-BIS(4,4, 5,5-tetramethyl-1, 3,2-dioxaborolan-2-yl) STILBENE, also known as (E)-1,2-bis [bis(2,3-dimethylbutyl)borano]styrene, it is an organic boron compound.
Nature:
(E)-A-Styrene bis (2,3-dimethyl-2,3-butanediol) ethyl diborate is A colorless to light yellow crystalline or powdery solid. It is stable at ambient temperature and soluble in non-polar solvents such as diethyl ether and ethyl acetate.
Use:
(E)-A-styrene diborate bis (2,3-dimethyl -2,3-butanediol) ethyl ester is an important reagent in organic synthesis, commonly used to catalyze the transfer of styrene groups. It can participate in the boron-boron bond exchange reaction to form a new carbon-carbon bond, thereby achieving the transfer of styrene groups to other compounds. This reaction is commonly used in the synthesis of organic compounds, especially in the field of total synthesis and pharmaceutical synthesis.
Method:
(E)-A-styrene bis (2,3-dimethyl -2,3-butanediol) ethyl diborate can be obtained by styrene and dimethyl -2, 3-Butanediol is obtained by reaction in the presence of boric acid. The reaction temperature is generally from room temperature to 60°C.
Safety Information:
(E)-A-Styrene bis (2,3-dimethyl-2,3-butanediol) ethyl diborate is relatively safe under proper use and storage conditions. However, as a chemical agent, it still has some potential dangers. Care should be taken to prevent contact with skin and eyes, and to ensure that the operation is carried out in a well-ventilated place. If inhaled or ingested, seek medical assistance immediately. For detailed Safety operation guidelines, please refer to the relevant Safety Data Sheet.
Please note that when using any chemical substances, you should follow the correct safety procedures and operate under the guidance of professionals.
