“…For instance, Li, Wang and co-workers described a closely related concept based on C-H activation reaction instead of the insertion of the palladium in the aryl halide bond. (Scheme 30) [44] In this reaction, acetamides serves as an orthodirecting group for the palladium insertion. Then, thanks to a Pd II /Pd III /Pd IV cycle, the ortho-carbonylation is possible on several acetamides 189 in good yields.…”

Carbon–carbon bond formation reactions are of longstanding interest in organic chemistry. Improvements of the methods targeting its creation are still being performed, especially thanks to the development of innovative methodologies in transition metal catalysis and photocatalysis. This review will tackle the combination of transition metal and photoredox cycles to create carbon–carbon bonds, focusing on the four transition metals most reported in the literature in this domain: Ni, Pd, Au and Cu.

“…Li, Wang et al reported decarboxylative o-acylation of acetanilides with α-oxocarboxylic acids as an acyl radical source (Scheme 62). [246] Eosin Y (3 mol-%) was used for photo-oxidation of α-oxocarboxylic, and O 2 as sacrificial oxidant. The presence of an amide-directing group in combination with Pd(OAc) 2 allowed the ortho-C-H activation of the aryl substrate.…”

A Retrosynthetic Approach for Photocatalysis

et al. 2020

Visible‐light‐mediated chemical reactions have become very popular within the last 15 years. Many excellent reviews have summarized reaction principles and recent results in photochemistry and photocatalysis. However, despite their popularity photochemistry and photoredox catalysis are not regular parts of the bachelor and master curriculum of chemistry education. As a consequence, most chemists will use in synthesis planning classic retrosynthetic disconnections and only rarely consider photocatalytic steps. The aim of this article is to be a useful tool for synthetic chemists, that are interested in the synthetic aspects of photocatalysis and looking for a specific retrosynthetic disconnection. Not only are informative schemes provided but also are the availability of the catalysts and reagents as well as the functional group tolerance of the respective method briefly discussed.

Because of the unique properties and wide applications, continuing efforts have been devoted to developing simpler and cleaner methods for the synthesis of organophosphorus compounds. Recently, transition metal-catalysed dehydrogenative coupling has been emerging as one of the powerful methodologies for constructing chemical bonds. Herein, we highlight the recent progress in the preparation of organophosphorus compounds via transition metal-catalysed dehydrogenative couplings of P(O)H compounds with Z-H compounds.
