Palladium‐Catalyzed Cross‐Coupling Reaction by Means of Organogermanium Trichlorides

“…[5] It further turned that the reaction could also be promoted by alkali hydroxide. [6] We report here our results on the palladium-catalyzed cross-coupling reaction using readily available organogermanium trichlorides [7] in aqueous alkaline solution. [8] ð1Þ…”

New biosurfactants based on germylated fatty compounds

“…Phenylgermanes were prepared according to literature procedures. [18] AIBN (azo bis-isobutyronitrile: [Me 2 C(CN)-N ) 2 was used in 1% concentration relative to organic reagents. NMR spectra were recorded in CDCl 3 at 20…”

“…[17] Radical initiators and transition metal catalysts are well known to be effective in accelerating hydrometalations. [18] Although hydrogermylation of alkenes, carbonyls and α,β-unsaturated carbonyl compounds have been reported, there are no reports of hydrogermylation of unsaturated FAME. In order to optimize the reaction conditions, we first investigated the hydrogermylation of methyl 10-undecenoate with triphenylgermane (Scheme 1).…”

Beiträge zur Chemie der Carbonylkomplexe mit Germanium-bzw. Zinn-Übergangsmetall-Bindungen/ Contributions to the Chemistry of Carbonyl Complexes with Germanium or Tin Transition Metal Bonds

“…Verbindungen des Typs X2E[ML"]2 (E = Ge, Sn, Pb; M = Übergangsm etall; X = Halogen, Ph) sind ausführlich beschrieben und wegen ihrer katalytischen V erw endbarkeit ebenso von Interesse wie als Modell für einfache Cluster [1][2][3]. W ährend die Verbindungen mit gleichen Übergangsm etallresten auf den verschiedensten W e gen synthetisiert werden können, sind die polym etal lischen Spezies mit unterschiedlichen Carbonylm etallatresten am H auptgruppenm etall am besten durch Salzeliminierung der Thallium (I)carbonylm etallate mit den entsprechenden Trihalogenoverbindungen des Ge, Sn und Pb zu erhalten [4,5].…”
