I am just ran a reaction using bromoform as the solvent (to form a dihalocarbene), but am having a difficult time removing it. the compound I formed is less volatile than bromoform but not by much. I have tried silical column and kughelror distillation and just lengthy rotoevap sessions with heated bath (53 degrees C) followed by high vac. and azeotroping with DCM but it is still significant by NMR. anybody have any tips?
