Recent applications of the Suzuki–Miyaura cross-coupling reaction in organic synthesis

“…Another heterocyclic carbene complex of type 15 has been used for the SM coupling of aryl chlorides, with turnover frequencies up to 552. 29 Trudell and co-workers 30 have found that the SM crosscoupling reaction of the arylboronic acids with nonactivated aryl chlorides occurs at 808C in high yields if catalytic amounts of Pd 2 (dba) 3 and the sterically crowded imidazolium salt 16 are combined with Cs 2 CO 3 in dioxane. Both sterically hindered and electron-rich aryl chlorides were found to couple with arylboronic acids in high yields.…”

Polyimide-Supported Dichloro-1,3-bis(p-dimethylaminobenzyl)benzimidazolidin-2-ilidenruthenium (II) as Effective Catalyst for Hydrosilylation Reactions

“…These properties have led to a number of applications where NHC-based catalysts exhibit superior performance. Such NHC-metal complexes have been successfully utilized in cross-coupling reactions [16] and related processes, including hydrogenation [17], hydroformylation [18] hydrosilylation [19], oxidation [20], metathesis [21], cycloisomerisation of olefins [22], the synthesis of furans [23] and cyclopropanation reactions.…”

Novel tetrahydropyrimidinium / palladium system as a convenient catalyst: Suzuki coupling reactions of aryl chlorides

“…[15][16][17] Palladium-catalysed cross-coupling reactions are particularly attractive because of their versatility for formation of C-C bonds. [18][19][20] Sterically hindered, electron-rich alkyl phosphines 21 and carbene 22 ligands have received growing interest in recent years. Yet, the phosphine ligands and the phosphine-palladium complexes are labile to air and moisture at high temperatures, placing significant limits on their synthetic utility.…”
