(2E)-3-[3,5-Bis(trifluoromethyl)phenyl]-2-propenoic acid - Introduction
trans-3,5-bis(trifluoromethyl)cinnamic acid, also known as trans-3,5-bis(trifluoromethyl)cinnamic acid, the chemical formula is C14H8F6O2. The following is a description of the properties, uses, preparation and safety information of the compound:
Nature:
- trans-3,5-bis(trifluoromethyl)cinnamic acid is a colorless crystalline solid.
-It has good solubility and can be dissolved in organic solvents (such as methanol, ethanol and dichloromethane).
-This compound is stable and its melting point is about 130-132 degrees Celsius.
Use:
- trans-3,5-bis(trifluoromethyl)cinnamic acid can be used as a reagent and intermediate in organic synthesis.
-It can be used to prepare compounds with pharmaceutical activity, such as antibacterial agents and pesticides.
-In addition, it can also be used for C- C bond formation reactions in organic synthesis, such as cross-coupling reactions and C- H functionalization reactions.
Method:
- trans-3, the preparation of 5-bis(trifluoromethyl)cinnamic acid is usually obtained by chemical synthesis.
-A common synthesis method is to react trifluoromethyl cinnamic acid with trifluoromethylating reagents, such as trifluoromethylated sulfoxide (CF3SO2CF3) or trifluoromethylated sulfoxide (CF3SO2OCF3).
-In the reaction, the trifluoromethylating reagent is usually added to the solution of trifluoromethyl cinnamic acid, and the reaction is carried out under appropriate conditions, such as under an inert gas atmosphere, the control of reaction temperature and time is very important.
Safety Information:
-Due to the trans-3,5-bis(trifluoromethyl)cinnamic acid has not been widely studied and applied, and its specific safety information and toxicity data are relatively limited.
-When using this compound, follow laboratory safety procedures.
-It may be irritating to the eyes, skin and mucous membranes, so appropriate protective measures, such as wearing protective glasses and gloves, are required when exposed.
-If taken by mistake or inhaled, seek medical attention immediately. When using or storing, keep away from heat sources and flames to avoid fire or explosion hazards.
