Ni/Pd-catalyzed Suzuki–Miyaura cross-coupling of alcohols and aldehydes and C–N cross-coupling of nitro and aminesviadomino redox reactions: base-free, hydride acceptor-free

Abstract

A new Ni/Pd bimetallic multifunctional catalytic system has been developed for the domino Suzuki–Miyaura cross-coupling of benzyl alcohols with phenyl boronic acid and domino reduction C–N cross-coupling of the nitro compounds with aryl halides.

Catalytic filtration: efficient C-C cross-coupling using Pd(II)-salen complex-embedded cellulose filter paper as a portable catalyst

“…S1c †). 23,24,26 Substitution of methyl imidazolium groups has caused a series of stretching vibrations related to the C-H of the imidazole ring at 1500-2950 cm À1 in agreement with the literature (Fig. S1d †).…”

“…S1b †), in agreement with the literature. 24,25 The salen ligand (3) was characterized by the shi of the peak belonging to the aldehyde group towards weaker vibrations due to the formation of C]N bond at 1635 cm À1 . 25,26 Also, the peaks related to C-I and C-H (aliphatic) and C-H (aromatic) have appeared at 582 cm À1 , 3078 cm À1 and 2916 cm À1 , respectively (Fig.…”

Efficient reduction of nitro compounds and domino preparation of 1-substituted-1H-1,2,3,4-tetrazoles by Pd(ii)-polysalophen coated magnetite NPs as a robust versatile nanocomposite

“…In situ XPS analysis was also performed at 30 min of the nitrobenzene reduction reaction. The results well show the presence of Pd(0) species in the respective binding energies at 342.5 eV (Pd 3d 3/2 ) and 335.2 eV (Pd 3d 5/2 ), 35 along with Pd 2+ species ( Fig. 8b ).…”

“…The presence of peaks at binding energies of 342 and 337 eV in the high resolution XPS analysis clearly shows that the Pd centers have a capacity of +2 (ref. 35 ) and no impurities were found arising from the presence of other species in the catalyst ( Fig. 1c ).…”

Magnetic Fe3O4@Ag nanoparticles catalyzed C–C cross‐coupling reaction of aromatic alcohols

“…Considerable effort has been made to develop heterogeneous catalytic systems for alcohol oxidation such as Au-Pd alloys, Ni/Pd bimetallic catalysts, and so on. [15][16][17][18] Although noble metal catalysts show high activity in the conversion of alcohols, they are quite expensive and suffer from deactivation and instability. Compared with noble metal catalysts, silver-containing catalysts may be a good alternative because it is much cheaper than other precious metals.…”
