A novel palladium(0) complex; bis(dibenzylideneacetone)palladium(0)

Stereospecific synthesis of a family of novel (E)‐2‐aryl‐1‐silylalka‐1,4‐dienes or (E)‐4‐aryl‐5‐silylpenta‐1,2,4‐trienes via a cross‐coupling of (Z)‐silyl(stannyl)ethenes with allyl halides or propargyl bromide

“…Bis(dibenzylideneacetone)palladium(0) was prepared according to the literature method. [65] N,N-dimethylformamide (DMF) was distilled from calcium hydride before use. 1,2-Dimethoxyethane and tetrahydrofuran (THF) were kept over 4 Å molecular sieves and distilled over lithium aluminum hydride just before using.…”

Palladium Nanoscale Catalysts in Ionic Liquids: Coupling and Hydrogenation Reactions

“…Reduction with dihydrogen or hydrides (D-E; X = OAc, halide) or reductive elimination of a palladacycle by reaction with a diene (F). Adapted from references (Takahashi et al, 1970;Reetz & Westermann, 2000;Xu et al, 2000;Deshmukh et al, 2001;Cassol et al, 2005;Umpierre et al, 2005).…”

“…(Reetz & Westermann, 2000;Rocaboy & Gladysz, 2003;Tromp et al, 2003) The first article of a zero-valent Pd complex suitable for the formation of Pd-NPs, by Takahashi and co-workers was published in 1970, used Pd(dba) 2 (dba = dibenzylideneacetone) under thermal decomposition conditions forming metallic palladium and dba in solution. (Takahashi et al, 1970) More studies of Pd-NP synthesis and its applications followed in the 1980s and 1990s by, for example Bönnemann, Reetz and their respective co-workers. (Bonnemann et al, 1990;Bonnemann et al, 1991;Reetz & Helbig, 1994;Reetz & Quaiser, 1995;Reetz & Lohmer, 1996) In the last decade, metal NP synthesis in ILs had their breakthrough and numerous detailed studies about PdNPs in ILs are available in the literature.…”

“…(Bonnemann et al, 1990;Bonnemann et al, 1991;Reetz & Helbig, 1994;Reetz & Quaiser, 1995;Reetz & Lohmer, 1996) In the last decade, metal NP synthesis in ILs had their breakthrough and numerous detailed studies about PdNPs in ILs are available in the literature. Synthetic approaches using controlled thermal decomposition for the generation of Pd-NPs in ILs use for example: Pd(dba) 2 , (Takahashi et al, 1970) Pd(OAc) 2 or palladium carbene complexes (Scheme 3). (Reetz & Westermann, 2000;Xu et al, 2000;Deshmukh et al, 2001; Furthermore, palladium salts such as PdCl 2 , Na 2 PdCl 4 can be reduced with metal hydrides or simply dihydrogen.…”

Synthesis of Novel Palladacycles Inhibitors of the Cathepsin B Activity and Antitumoral Agents

“…Reactions were carried out without precautions to exclude atmospheric moisture, unless otherwise stated. The IR and C, H, N Elemental analyses and melting point determinations were carried out as described elsewhere [69]. NMR spectra were recorded on Varian Unity 300 and a Bruker Unity 200 instruments.…”
