results in the formation of 4,5-dianilino-1,2-benzoquinone and the anil of , (). The C-4 substituent is efficiently cleaved and mechanisms are proposed to account for this phenomenon based on HPLC and GC studies and the formation of N-methylaniline when these reactions were performed in the presence of sodium cyanoborohydride. The evidence suggests that the initial step involves the addition of aniline
