Copper-catalyzed rearrangement of oximes into primary amides
Sumeet Kumar Sharma, Simon D Bishopp, C L Allen, R Lawrence, M J Bamford, A A Lapkin, Pawel Plucinski, R J Watson, Jonathan M J Williams
Aug 17, 2011
The atom-efficient and cost-effective rearrangement of oximes into primary amides is catalyzed by simple copper salts. The use of homogeneous Cu(OAc)(2) (1-2 mol %) was found to be effective for this transformation at 80 C. The...
