The reactions of N,N-dioxyenamines with carboxylic and sulfonic acid anhydrides were investigated. A newmethod for the synthesis of α-hydroxyoxime derivatives via the reaction of N,N-dioxyenamines with trifluoroacetic anhydride is described. 1,2-oxazine - trifluoroacetic anhydride - hydroxyoxime - enamine - rearrangement
Formal aromatic C−Hinsertion of rhodium(II) carbenoid was intensively investigated to develop a new methodology and probe its mechanism. Contrasting with the previously proposed directC−Hinsertion, the mechanism was revealed to be electrophilic aromatic substitution, which was supported by substituent effects on the aromatic ring and a secondary deuterium kinetic isotope effect. Various isoquinolinones

The linear [M(CN)2]− (M = Au, Ag) anions can be used as metalloligands in oxime-based Mn chemistry to afford 1D chains of [MnIII6] single-molecule magnets (SMMs).
