The reaction between tertiary α-bromo ketones or aldehydes and silver tetrafluoroborate in ether affords α-fluorocarbonyl compounds. Neighboring group participation by the carbonyl oxygen is proposed to account for the products and by-products.

Compounds that demonstrate chelation affinity and selectivity for first transition series elements are administered to patients suffering from such conditions as ischemia, prolonged seizures and trauma to provide neuroprotection, cardioprotection, or both. These compounds when administered form complexes with chelatable iron and copper cations and thereby mitigate the ability of these cations to catalyze Haber-Weiss reactions that form toxic hydroxy free radicals that cause tissue injury. These compounds also form complexes with chelatable zinc cations thereby inhibiting the cytotoxicity associated with excess chelatable zinc.

This invention involves the use of a class of compounds with chelation affinity and selectivity for first transition series elements. Application or administration of the free or conjugated compound, or physiological salts of the free or conjugated compound, results in decrease of the bioavailability and/or chemical action of first transition series elements. These characteristics make such compounds useful in cosmetics and personal care products to decrease odor arising from microbial growth on body surfaces and in body cavities, decrease microbial growth on teeth, plaque, and gums that cause tooth decay and gum disease, inhibition of oxidative damage to the skin, inhibition of enzymatic action of metalloenzymes dependent on first transition series elements, and inhibition of reperfusion injury.
