Abstract
Abstract The products of nitration of 2,3-diphenylindole depend on whether the reaction is carried out in acetic or sulphuric acid solution. The 6-nitro derivative is the only product in the first case, while in the second case 3-( p -nitrophenyl)-2-phenylindole is the first product, which is nitrated further into 5-nitro-3-( p -nitrophenyl)-2-phenylindole. Sulphuric acid nitration of 2-methyl-3-phenyl- indole takes a similar course, while that of 3-methyl-3-phenylindole gives the 5-nitro derivative in 80% yield, no nitration of the 2-phenyl substituent taking place.
