The rhodium-catalyzed oxidative acylation between secondary benzamides and aryl aldehydes via sp2 C - H bond activation followed by an intramolecular cyclization is described. This method results in the direct and efficient synthesis of 3-hydro
Lawesson's reagent for direct thionation of hydroxamic acids: Substituent effects on LR reactivity

To explore the generality and scope of direct thionation of hydroxamic acids (HAs), the reaction of various structurally diverse HAs with Lawesson's reagent was investigated. The yield of thiohydroxamic acid (THAs) is poor when HAs possess bulky acyl and/or N-substituents, acidic α-hydrogen atoms, or an N-phenyl ring. THAs yields were correlated with Brown sigma parameter. The relative rates of two subsequent processes kT2 and kR2 were also measured. Correlation was also found for methine proton chemical shifts of N-isopropyl benzothiohydroxamic acids.
