title: 2,3-migration in Rh(II)-catalyzed reactions of beta-trifluoroacetamido alpha-diazocarbonyl compounds.
abstract: [Structure: see text] The hydroxy group was directly converted into the trifluoroacetamido group by reacting beta-hydroxy-alpha-diazo carbonyl compounds with trifluoroacetimidoyl chloride in the presence of DBU. Rh(II)-catalyzed reactions of these diazo compounds gave 2,3-migration products in high yields.
