Fluorinated Aliphatic Diazirines: Preparation, Characterization, and Photolabeling Studies

Abstract

The previously unknown difluoromethyl- and the previously neglected trifluoromethyl-aliphatic diazirines were synthesized and characterized. Model photolabeling experiments and biological studies revealed that the stable trifluoromethyl-aliphatic diazirines could indeed be safely used as photoaffinity labels, while the labile difluoromethylated analogues - could not.
