2-Arylnaphthoxazole-derived palladium(II) complexes as phosphine-free catalysts for Heck reactions

Ruthenium‐Catalyzed Synthesis of Allylic Alcohols: Boronic Acid as a Hydroxide Source

“…(E)-Ethyl-3-(naphthalen-2-yl)acrylate: [29] 99 %. (E)-Ethyl-3-(naphthalen-1-yl)acrylate: [32] (E)-Ethyl-3-(2,4,6-trimethoxyphenyl)acrylate: [33] (E)-Ethyl-3-(4-(N,N-dimethylamino)phenyl)acrylate: [29] (E)-Ethyl-3-(4-benzyloxy)phenyl)acrylate: [31] (E)-Ethyl-3-(4-methoxyphenyl)acrylate: [29] 86 %. General procedure for the synthesis of allylic alcohol: To a solution of ester (10 mmol, 1 equiv) in toluene (70 mL), diisobutylaluminum hydride (2 equiv) was slowly added at À78 8C.…”

Reactivity of 2-(2-hydroxyphenyl)benzoxazole and 2-(2-hydroxyphenyl)benzothiazole towards group 10 transition metals. Evaluation in palladium catalyzed Suzuki–Miyaura C–C couplings

“…The presence of the phenolic group allows stabilization of higher oxidation states due to the σ-donor properties of this fragment [18]. showing moderate to high activities [19][20][21][22]. In this line, cross coupling reactions have been recognized as true power tools in organic synthesis and palladium and nickel complexes have been widely used as catalyst in these reactions [23][24][25][26].…”

Polymer‐supported palladium complexes with C,N‐ligands as efficient recoverable catalysts for the Heck reaction

“…However, most of the phosphine ligands are air‐ and moisture‐sensitive. It is therefore not surprising that much effort has been devoted to the development of new catalytic systems for this reaction 8–16. From an economic point of view, the recovery and reuse of the noble metal catalysts are highly important.…”
