4-Ethyl-4'-iodobiphenyl → N,N'-di-p-tolyl-N,N'-di(4'-ethylbiphenyl-4-yl)-3,3'-dimethylbenzidine

Participants

Reaction Steps

According to the same manner as that described in Synthesis Example 1, 14.9 g of N,N'-diacetyl-3,3'-dimethylbenzidine was reacted with 21.8 g of para-iodobenzene to give N,N'-di-p-tolyl-3,3'-dimethylbenzidine. Further, 12.0 g of N,N'-di-p-tolyl-3,3'-dimethylbenzidine was reacted with 15.4 g of 4-ethyl-4'-iodobiphenyl according to the same manner as that described in Synthesis Example 1 to give N,N'-di-p-tolyl-N,N'-di(4'-ethylbiphenyl-4-yl)-3,3'-dimethylbenzidine (hereinafter referred to as 6-c) (8.82 g, yield: 23.7%).
