General description

Vapour pressure as a function of temperature for 1-bromo-4-iodobenzene has been studied using a diaphragm manometer and torsion mass-loss effusion.

Application

1-Bromo-4-iodobenzene has been employed:
  • as reagent for in situ desilylation and coupling of silylated alkynes
  • as starting reagent in the total syntheses of ent-conduramine A and ent-7-deoxypancratistatin (alkaloids)
  • as substrate in copper-free Sonogashira coupling in aqueous acetone
  • in synthesis of β,β,dibromostyrenes
