Metal/metal dual catalysis provides new viewpoints and opportunities for C−H functionalization, especially in reactivity and selectivity control aspects. It helps to realize sequential or cooperative catalytic transformations in one‐pot, shortening the synthetic steps in target molecules construction. This micro‐review summarizes the most recent advances in this research field, discusses related mechanism, collecting examples according to the role of the metal species.

“…Some selected examples are as illustrated in Scheme 9. 75 Fu, Chen, and co-workers disclosed the first example of the stereodivergent synthesis of alkenylpyridines 42 using a Pd/Cu dual catalytic system through the activation of pyridinium salts 41 to alkenylate selectively at C2 of pyridines with internal alkynes 1. Significantly, the configuration of the resulting alkenylpyridines could be tuned by choosing the appropriate N-alkyl groups of the pyridinium salts, enabling the synthesis of both Z-and E-alkenylpyridines 42 with high regio-and stereoselectivities (Scheme 10).…”

Coupling reactions stand amid the most significant reactions in synthetic organic chemistry. Of late, these coupling strategies are being viewed as a versatile synthetic tool for a wide range of organic transformations in many sectors of chemistry, ranging from indispensable synthetic scaffolds and natural products of biological significance to novel organic materials. Further, the usage of dual-catalysis in accomplishing various interesting cross-coupling transformations is an emerging field in synthetic organic chemistry, owing to their high catalytic performance rather than the usage of a single catalyst. In recent years, synthetic organic chemists have given considerable attention to hetero-dual catalysis, wherein these catalytic systems have been employed for the construction of versatile carbon-carbon [C(sp3)–C(sp3), C(sp3)–C(sp2), C(sp2)–C(sp2), etc.] and carbon-heteroatom (C-N, C-O, C-P, C-S, etc.) bonds. Therefore, in this mini-review, we are emphasizing recently developed various cross-coupling reactions catalysed by transition-metal dual-catalysis (i.e., using palladium and copper catalysts, and by omitting the reports on photoredox/metal catalysis).

Initially, people observed macroscopic natural phenomena with the naked eye and summarized the laws of nature [1][2]. Humans then use magnifying glasses and microscopes to observe some microscopic objects.…”

In optical research, the birth of laser has brought unprecedented development to the field of optics. This technology has been fully developed and applied when lasers have been developed and studied for a long time in the field of traditional spectroscopy. In addition, a lot of very important information can be received that cannot be obtained by these classical methods. The purpose of this paper is to study the two-dimensional third-order nonlinear laser spectroscopy of fused heterocyclic derivatives. A new method for third-order nonlinear laser spectroscopy, and in order to judge the accuracy of the method, the cascaded equation of motion method is used for comparison. The experimental results show that the time non-local quantum master equation is a relatively accurate method for solving the time evolution of the density matrix, so the matching method can obtain accurate two-dimensional third-order spectrum when solving the spectrum.
