title: Metal ion promoted tautomerization and C-N bond cleavage: conversion of catechol to a p-benzoquinone derivative.
abstract: Metal ion promoted tautomerization of p-iminoquinone to o-diiminoquinone and a C-N bond cleavage of 2,5-bis(p-tolylamino)-4-p-tolyliminobenzoquinone leading to the conversion of catechol to a p-benzoquinone derivative are reported.
