Provided is a photoinitiator represented by Formula 1: The photoinitiator is suitable for photocrosslinking. Further provided is a photosensitive resin composition including the photoinitiator. The photoinitiator and the photosensitive resin composition have improved solubility and high sensitivity. The photosensitive resin composition is suitable for use in the production of black resists, color resists, overcoats, column spacers, and organic insulating films for LCDs.

transition metals are necessary in the reaction of in situ generated arynes with nitrosoarenes to give substitutedcarbazoles. Depending on the fluoride source and the solvent, either N‐arylated carbazoles or NH‐carbazoles are obtained (see scheme; DME=dimethoxyethane, OTf=trifluoromethanesulfonate). In these cascades a CC and one or two CN bonds are formed. The reactions are easy to conduct and proceed

Despite their intrinsic instability, 4a-alkyl-4aH-carbazoles can be generated by a catalytic dearomatisation process; their reactivity is demonstrated by facile dealkylation and highly unusual cyclodimerisation processes.

Disclosed is a process for the preparation of N-alkyl carbazole. Said process comprises: a) chlorinating cyclohexanone to form 2-chlorocyclohexanone; b) reacting 2-chlorocyclohexanone with N-ethyl aniline to form 2-(N-ethyl anilino) cyclohexanone; c) cyclizing 2-(N-ethyl anilino) cyclohexanone by refluxing with simultaneous water removal to obtain 9-ethyltetrahydrocarbazole; d) treating 9-ethyl-tetrahydrocarbazole with concentrated hydrochloric acid followed by water wash for removing N-ethyl aniline; e) dehydrogenating 9-ethyltetrahydrocarbazole by heating 9-ethyltetrahydrocarbazole in a solvent, in presence of a catalyst to obtain N-alkyl carbazole.
