Benzal chloride is an organic compound with the formula C6H5CHCl2.[1] This colourless liquid is a lachrymator and is used as a building block in organic synthesis.
Benzal chloride is produced by the free radical chlorination of toluene, being preceded in the process by benzyl chloride and followed by benzotrichloride
- C6H5CH3 + Cl2 â C6H5CH2Cl + HCl
- C6H5CH2Cl + Cl2 â C6H5CHCl2 + HCl
- C6H5CHCl2 + Cl2 â C6H5CCl3 + HCl
Most benzal chloride is hydrolysed to benzaldehyde:[2]
- C6H5CHCl2 + H2O â C6H5CHO + 2 HCl
Addition of strong base to benzal chloride generates phenylcarbene.
