Air-stable imidazole-imine palladium complexes for Suzuki–Miyaura coupling: Toward an efficient, green synthesis of biaryl compounds

A novel 4-aminoantipyrine-Pd(II) complex catalyzes Suzuki–Miyaura cross-coupling reactions of aryl halides

“…There have been ongoing efforts to develop a stable and efficient Pd catalyst for these reactions. Recently, palladium complexes containing imidazole-imines [ 12 ], binary nanoclusters [ 13 ], N-heterocyclic carbenes (NHCs) [ 14 ], nanoparticles [ 15 ], palladacycles [ 16 ], and Schiff bases [ 17 ] have been developed as highly effective phosphine-free catalysts for SM coupling reactions.…”

CH⋯Pd interactions: One dimensional heteropolynuclear complexes

“…Squareplanar geometry tetracyanopalladate(II) anions have attracted attention as catalysts in CAC coupling reactions [6]. Since palladium complexes display a behavior as catalyst such as the Suzuki-Miyaura and the Heck-Mizoroki coupling reactions [7][8][9], cyanide complexes containing palladium central atoms can be used to increase the yield of these reactions.…”

Features of polychlorinated biphenyls nitration

“…Mononitro [12,13] and dinitro [14] derivatives of biphenyl have been described. The mononitro derivatives are commonly prepared indirectly from the mononuclear derivatives [13] rather than via direct nitration of biphenyls.…”

“…The mononitro derivatives are commonly prepared indirectly from the mononuclear derivatives [13] rather than via direct nitration of biphenyls. A method of 4-nitrobiphenyl production with the yield of 84% upon biphenyl treatment with a mixture of sodium nitrite and an acid (the elemental formula CH 0.35 O 0.35 S 0.14 ) at room temperature has been described in [15].…”
