Herein we reported a method for copper pivalate mediated, directed functionalization of ortho C−H bonds in (2- methylthio)aniline benzamides. Diaryl disulfides were used for thiolation, while successful phenoxylation was obtained with phenol as the coupling agent. Our report marks a rare example for flexible transformation of benzamide C(sp2 )−H bonds into the corresponding unsymmetrical diaryl ethers and thioethers.

The electronic states of FeSin −/0/+ (n = 1-2) clusters have been investigated with DFT, CASPT2, and DMRGCASPT2 methods. By using relatively large active spaces, the DMRG-CASPT2 method is found to provide highly accurate relative energies for the various relevant electronic states. Leading configurations, bond distances, harmonic vibrational frequencies, and relative energies for the low-lying states of the title clusters are reported.
