General description

2-Chloro-1-fluoro-4-nitrobenzene undergoes reduction in the presence of Mo(CO)6 and 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) under microwave irradiation to yield a mixture of 3-chloro-4-fluoroaniline and 3-chloro-4-ethoxyaniline[1].

Application

2-Chloro-1-fluoro-4-nitrobenzene has been used in synthesis of:
  • benzoimidolones on Ameba resin[2]
  • methyl 6,7,8,9-tetrahydropyrido[1,2-a]indol-10-ylacetate[3]
