title: 2,3-Dichloro-5,6-dicyano-1,4-benzoquinone-catalyzed reactions employing MnO2 as a stoichiometric oxidant.
abstract: Several oxidative reactions can be effected with MnO(2) in the presence of substoichiometric quantities of DDQ. These transformations include oxidative cyclization, deprotection, and dehydrogenation reactions. The use of MnO(2) as a terminal oxidant for DDQ-mediated reactions is attractive based on economical and environmental factors.
