Both carbon-13 and nitrogen-15 solid-state NMR spectroscopy have been employed to characterize the carbonyl carbon and nitrogen chemical shift (CS) tensors of the amide fragment of (Z)-acetanilide (I) and (E)-N-methylacetanilide (II). These two related co

A useful transformation of nitriles to N-phenyl amides has been achieved through a novel intermolecular phenyl transfer reaction from phenyl hydrazides and N-addition to nitriles in the presence of PIFA under mild and solvent-free conditions. This cross-coupling reaction includes the oxidative cleavage of sp2 C-N bonds of phenyl hydrazides to form a phenyl radical and the subsequent N-addition to cyanos to form new sp2 C-N bonds and provides efficient access to various N-phenyl amides in moderate to good yields under mild reaction conditions.

The dehydrogenative C-N cross-coupling of unprotected, secondary anilines through ortho-N-carbazolation has been achieved using a Ru catalytic system with O2 as the terminal oxidant. The reactions proceed in an intermolecular fashion, selectively in the ortho position. Implications for the field of organic synthesis are discussed. No-No-No: Amination of a non-acidic Ci￡H bond, no pre-activation of the coupling partners, no chelate-assisting directing group. Dehydrogenative C-N cross-coupling through the ortho-N-carbazolation of unprotected, secondary anilines has been achieved using a Ru catalyst with O2 as the terminal oxidant. The reactions proceed in an intermolecular fashion, selectively in the ortho position.

The cooperative action of Ru and Cu catalysts enables direct polynuclear C-H and N-H activation for the dehydrogenative N-carbazolation of carbazoles, selectively at the C1 position. Initial mechanistic experiments are presented and discussed.
Cross-dimerization of nitrosobenzenes in solution and in solid state

Cross-linking of nitrosobenzenes to heterodimers (azodioxides) when they are not sterically crowded with large groups in ortho-position was studied by NMR and FT-IR spectroscopy, X-ray crystallography as well as by cryogenic photolysis. It was found for the first time that cross-linked dimers (heterodimers) exist both in solution and in solid state and that they appear in the crystal together with homodimers. The system is used as a model for studying organic solid solution formation. The role of molecular packing in formation of a weak chemical bond is also discussed.
