A newly designed class of acridinium-based organophotocatalysts bearing an imide group at the C9-position is presented. To achieve these unprecedented structures, a synthetic strategy based on a novel straightforward oxidative Ugi-type reaction at the benzylic position of C9-unsubstituted acridanes was developed. The introduction of the imide-unit affords a notable photocatalytic activity enhancement, allowing efficient transformations in different oxidative and reductive visible-light catalytic reactions.

The solvolyses of 1-phenyl-2-propyl benzenesulphonates (PPBs) have been investigated in methanol-acetonitrile mixtures and in hexafluoropropan-2-ol (HFIP).The transition state structure has been discussed using various selectivity parameters, especially with the cross-interaction constants, ρYZ and λYZ, between substituents in the substrate (Y) and in the leaving group (Z).It has been found that the solvolysis proceeds by the solvent-assisted pathway, ks, in methanol, whereas in HFIP PPBs solvolyse via the aryl-assisted pathway, kΔ.The only exception was the p-MeO substituent, which deviates positively in methanol from the log ks vs. ? plot due to participation of the aryl-assisted path and negatively in HFIP from the log kΔ vs. ?(neophyl) plot due to deactivation by hydrogen bonding of the methoxy oxygen in the acidic solvent.The two distinctive high values of ρYZ provided evidence for the strongly bound transition states in the two processes, ks and kΔ, with a relatively low degree of bond breaking.
