Photolysis of 4',5'-dimethoxy-1,1':2',1''-terphenyl (3) in the presence of iodine gives 2,3-dimethoxy-triphenylene (4) (72percent).A similar photolysis of either 3,4-dimethoxy-3'',4',4'',5'-tetramethyl-1,1':2',1''-terphenyl (5) or 4',5'-dimethoxy-3,3'',4,4''-tetramethyl-1,1':2',1''-terphenyl (7) gives 2,3-dimethoxy-6,7,10,11-tetramethyltriphenylene (6).The regiospecificity of these photocyclisation reactions makes this the best route to asymmetrical 2,3,6,7,10,11-hexasubstituted derivatives of triphenylene.
