Norrish type II reactions of acyl azolium salts

The photochemical reactivity of acyl azolium salts derived from aliphatic carboxylic acids has been investigated. These species, which serve as models for intermediates generated in N-heterocyclic carbene (NHC) organocatalysis, undergo Norrish type II elimination reactions under irradiation with UVA light in analogy to structurally related aromatic ketones. Moreover, efficient Norrish-Yang cyclization was observed from an adamantyl-substituted derivative. These results further demonstrate the ability of NHCs to influence the absorption properties and photochemical reactivity of carbonyl groups during a catalytic cycle.

A METHOD FOR PRODUCING VINYLCYCLOALKANES COMPOUNDS

The present invention relates to a method for producing vinylcycloalkanes compounds represented by the general formula (5) highly selectively and economically, which comprises hydrogenation and dehydration. Hydrogenation step: hydrogenating the compounds represented by the general formula (1) or/and (2) or/and (3) or/and (4) with hydrogen to prepare the corresponding primary or secondary alcohols in the presence of hydrogenation catalyst with min. 0.1 part by wight. Dehydration step: dehydrating the corresponding primary or secondary alcohols prepared by the above-mentioned hydrogenation step to prepare vinylcycloalkanes compounds represented by the general formula (5) in the presence of dehydration catalyst. R 1 -CH2-CH2-OH (1) Wherein R 1 of the general formula (1)~(4) is hydrocarbyl (hydrocarbon functional group) having aromatic rings. R 2 -CH=CH2(5) Wherein R 2 of the general formula (5) is cycloalkyl or cycloalkyl-substituted alkyl.
