Abstract A series of alkynylgold(III) complexes with bis-cyclometalating ligand derived from ethyl 2,6-diphenylisonicotinate has been synthesized. The single crystal structure of one of the complexes revealed an unprecedentedly short Au(III)...Au(III) distance of 3.44 ?. These complexes were found to exhibit rich electrochemistry. Upon photoexcitation, the alkynylgold(III) complexes were found to show rich emission properties in various states at both ambient and low temperatures. One of the complexes have also been utilized as the light-emitting layer in the fabrication of organic light-emitting diodes, demonstrating the potentials and versatility of alkynylgold(III) complexes.

The NH4I-triggered formal [4 + 2] annulation of α,β-unsaturated ketoxime acetates with N-acetyl enamides has been developed. The current protocol employs electron-rich enamides as C2 synthons and enables the efficient and straightforward construction of polysubstituted pyridines in moderate to good yields based on metal-free systems. The reaction tolerates a wide range of functional groups and represents an alternate route toward the synthesis of pyridine derivatives.

A new method of FeCl2-catalyzed [4+2] annulation of α,β-unsaturated ketoxime acetates with N-acetyl enamides in batch and flow is reported. The current strategy features low-cost catalytic system, use of electron-rich olefins, operational simplicity, and broad substrate scope, thus providing a facile and efficient access to substituted pyridines in moderate to good yields.
