“…Based on kinetic studies [19][20][21] proving that the insertion of isocyanide into s-Pd-C bonds occurs by intramolecular migratory insertion of the s-C donor ligand into the previously coordinated isocyanide, we refluxed complex 2a in toluene with the hope of obtaining any of the dinuclear iminoacyl complexes resulting from insertion followed by dimerization with chloro 22 or iminoacyl bridging 23 ligands; both processes are known. However, 2a was recovered unchanged and none of the expected complexes, namely (9), was even detected by 1 H NMR.…”

“…1) in the SM coupling of sterically demanding and electronically deactivated aryl bromides with phenylboronic acid. The synthesis has been reported for: 1 [25][26][27], 2 [28], 7a [29], 7b-f [30] and 8-11 [31].…”

“…However, overall, most of these substrates show similar conversions with 6 as the precatalyst. For entry 4, the results were compared to an SCS symmetrical example [38,39], and the Herrmann-Beller catalyst [2] (figure 5), revealing that our unsymmetrical example shows favourable results under these catalytic conditions. Having the ability to couple the much more challenging aryl chlorides would have been advantageous due to their greater availability and cheaper cost; however, in this case 6 was not successful, even with the addition of tetrabutylammonium bromide.…”
