Iridium-catalyzed C?H activation and cyclization of naphthalen-1-amines with diazo compounds leading to naphtho[1,8-bc]pyridines have been developed. Different from the previous free-amine-directed C?H functionalization with diazo compounds that relied on the coordination of lone pair electrons or in situ formation of imine, this transformation passes through a five-membered iridacycle intermediate containing an N?Ir σ-bond. It offers an alternative approach for the synthesis of useful diverse naphtho[1,8-bc]pyridine derivatives in mild conditions. (Figure presented.).

Electrooxidative peri-C-H activation was accomplished by versatile ruthenium(ii) catalysis in terms of C-H/N-H and C-H/O-H functionalization. Thus, alkyne annulations proved viable with ample scope by organometallic C-H activation. The sustainable electrocatalysis exploited electricity, thereby avoiding the use of toxic transition metals as sacrificial oxidants. The robust ruthenium(ii)-electrocatalysis was operative in a protic alcohol/H2O reaction medium with excellent levels of position-, regio- and chemo-selectivity.
Copper-mediated dehydrogenative biaryl coupling of naphthylamines and 1,3-azoles

A copper-mediated dehydrogenative biaryl cross-coupling of naphthylamines and 1,3-azoles has been developed. The key to its success is the introduction of N,N-bidentate coordination system based on the picolinamide directing group. The reaction proceeds s
