1-Iodopyrene

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: The thus obtained N,N,N'-tris(4-methylphenyl)-N'-acetyl-3,3',5,5'-tetramethylbenzidine was hydrolyzed, and the hydrolyzed product and 1-iodo-pyrene were subjected to the same Ullmann reaction as in Preparation Example 1-6, whereby N,N,N'-tris(4-methylphenyl)-N'-(1-pyrenyl)-3,3',5,5'-tetramethylbenzidine (m.p. 198.0°-199.0° C.) was obtained.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
