Neopentyl bromide and pentaerythrityl tetrachloride were shown here to be non-mutagenic to 7 strains of Salmonella typhimurium. These inactivities are reflected in the inability of either compound to produce a colour reaction in the chemical alkylation test of Epstein (4-nitrobenzylpyridine

The recombination of chloromethyl and t-butyl radicals at room temperature was used to generate neopentyl chloride molecules with 89 kcal mol(-1) of internal energy. The observed unimolecular reactions, which give 2-methyl-2-butene and 2-methyl-1-butene plus HCl, as products, are explained by
