Nohr-McDonald elimination reaction |
摘要 |
A reaction for eliminating a functional group alpha to a carbonyl group. The reaction can be used to dehydrate a compound having an alcohol group alpha to a carbonyl group by reacting the compound in a non-aqueous non-polar solvent in the presence of an effective amount of a transition metal salt, such as zinc chloride, such that the alcohol group is dehydrated. This Nohr-MacDonald Elimination Reaction produces a light stable compound, which can be added to compositions for light stabilization of a colorant. The modified compound may be combined with a wave-length selective sensitizer.
