WebAbstract. The present intensive interest in the photochemistry of aromatic systems has its origins in observations reported in the late 1950s that benzene, contrary to the widely held opinion of the time, was photolabile and would undergo both isomerization (1) and addition (2) reactions when subjected to ultraviolet irradiation. WebThe key step in the synthetic methodology, namely the attachment of the carbohydrate residues to the cyclodextrin torus, proceeds in moderate-good yields (42-70%) by the photoaddition of thiol groups, positioned at the anomeric centers of the carbohydrate residues, to allyl ether functions on the cyclodextrins. greatland shoesWebVideo shows what photoaddition means.
