Abstract

Benzotrifluoride (BTF) is a suitable solvent substitute for carbon tetrachloride in experiments requiring application of bromine (Br₂) in free radical or addition reactions with organic substrates. A 1 M solution of Br₂ in BTF may be used to distinguish hydrocarbons based on the ease of abstraction of hydrogen atoms in thermally or light-induced free radical substitutions. Efficacy of minimization of solvent use, by aliquot addition to neat samples, has been established. This system also provides a useful matrix for testing unknowns for unsaturation or enolizable hydrogen atoms.
