Gold(I) complexes bearing ring-fused benzoxazine-derived triazolylidenes and their use in C–N bond-forming processes

We report the synthesis and full characterization of a novel series of ring-fused benzoxazine-derived triazolium salts (1a–c) and their corresponding triazolylidene gold(I) complexes (2a–c). All new compounds were fully characterized by means of 1H and 13C NMR spectroscopy, elemental analyses, and mass spectroscopy and in the case of triazoliums 1a and 1b by single-crystal X-ray diffraction. The new triazolylidene gold complexes (2a–c) were tested as precatalysts in the hydroamination and hydrohydrazination of terminal alkynes employing aniline derivatives and hydrazine as nitrogen sources, respectively.

Cp*Co(iii)-catalyzed annulation of azines by C-H/N-N bond activation for the synthesis of isoquinolines

Herein, an efficient, atom economic and external oxidant free approach has been disclosed for the synthesis of isoquinolines. Azines were employed for annulation reactions with alkynes via sequential C-H/N-N bond activation using an air-stable cobalt catalyst. The method takes advantage of the incorporation of both the nitrogen atoms of azines into the desired isoquinoline products, offering the highest atom economy. In addition, the developed protocol works under external oxidant as well as silver salt free conditions. Furthermore, the established methodology features a relatively broad substrate scope with high product yields and scalability up to the gram level.

Cs2CO3-mediated decomposition of N-tosylhydrazones for the synthesis of azines under mild conditions

Abstract: A facile, environmentally and efficient Cs2CO3-mediated decomposition of N-tosylhydrazones reaction has been developed for the synthesis of functionalized azines under mild conditions. This method offers broad substrate scope, occurs as additive-free, without strong base conditions, utilizes readily available reactants, and forms products in good to high yields.
