The Name is 4′-Hydroxyacetophenone. Through research, I have a further understanding and discovery of 99-93-4. Safety of 4′-Hydroxyacetophenone
A general and efficient protocol to synthesize substituted olefins from carbonyl compounds via nickel catalyzed C-O activation of enolates was developed. Besides ketones, aldehydes were also suitable substrates for the presented catalytic system to produce di- or tri- substituted olefins. It is worth noting that this approach exhibited good tolerance to highly reactive tertiary alcohols, which could not survive in other reported routes for converting carbonyl compounds to olefins. This method also showed good regio- and stereo-selectivity for olefin products. Preliminary mechanistic studies indicated that the reaction was accomplished through nickel catalyzed C-O activation of enolates, thus offering helpful contribution to current enol chemistry.
