A simple cobalt complex, such as Co(phen)Cl2, turned out to be a highly efficient and cheap precatalyst for a host of cross-coupling reactions involving aromatic and aliphatic organoaluminum reagents with aryl, heteroaryl and alkyl bromides. New C(sp2)–C(sp2) and C(sp2)–C(sp3) bonds were formed in good to excellent yields and with high chemoselectivity, under mild reaction conditions.

A gold-catalysed coupling of aryldiazoniumsalts with arylboronic acids is described. The reactions proceed in satisfactory yields under irradiation with blue LEDs in the presence of KF and a catalytic amount of ascorbic acid. Notably, 4-nitrobenzendiazonium tetrafluoroborate is sufficiently reactive to undergo the coupling with a variety of arylboronic acids in the absence of aryl radical initiators

We report a general and rapid chemoselective Kumada–Tamao–Corriu (KTC) cross‐coupling of aryl bromides in the presence of chlorides or triflates with functionalized Grignardreagents at 0 °C in 15 min by using Pd‐PEPPSI‐IPentCl (C4). Nucleophiles and electrophiles (or both) can contain Grignard‐sensitive functional groups (‐CN, ‐COOR, etc.). Control experiments together with DFT calculations suggest

reactive species involved in the reaction's path, in-depth mechanistic studies were carried out. It is further underlined that the CPN has greater catalytic efficiency based on its exceptional resistance to 50 substrates of varying functionality, for 5 consecutive catalyst recycling cycles as well as bulk-scale reactions and a turnover frequency value of up to 1840 h−1 at a low catalyst dose of Pd (0.0125
