Potassium isopropoxide: For sulfination it is the only base you need!

PEPPSI max: KOiPr has been identified as the key ingredient for Pd-catalyzed sulfination (see scheme). Potassium is essential to keep the thiol concentration low, and isopropoxide is necessary for precatalyst activation and to break up Pd-sufide-based resting states. Together with the reactive Pd-PEPPSI-IPentCl o-picoline catalyst, this system couples profoundly deactivated partners at RT that other catalysts cannot accomplish in refluxing toluene. Copyright

Process for preparing 2-amino-5-nitrophenol derivatives
-
, (2008/06/13)
A process for efficiently preparing 2-amino-5-nitrophenol derivatives in which benzoxazole derivatives are subjected to nucleophilic substitution reaction at the 5 position thereof to obtain corresponding benzoxazole derivatives, and the oxazole ring of the benzoxazole derivatives is then subjected to ring-opening to obtain 2-amino-5-nitrophenol derivatives. The 2-amino-5-nitrophenol derivatives are useful as industrial starting materials, reducing agents or antioxidants and intermediates for cyan-image-forming couplers.
