Base-free Knoevenagel condensation catalyzed by copper metal surfaces.
For the first time Knoevenagel condensation has been catalyzed by elemental copper with unexpected activity and excellent isolated yields. Inexpensive, widely available copper powder was used to catalyze the condensation of cyanoacetate and benzaldehyde under mild conditions. To ensure general applicability, a wide variety of different substrates was successfully reacted.

متن کاملMetal-mediated coupling of a coordinated isocyanide and indazoles.
A reaction between equimolar amounts of cis-[PdCl2(CNCy)2] (1) and indazole (HInd, 2) or 5-methylindazole (HInd(Me), 3) proceeded in refluxing CHCl3 for ca. 6 h affording the aminocarbene species cis-[PdCl2{C(Ind)=N(H)Cy}(CNCy)] (4) or cis-[PdCl2{C(Ind(Me))=N(H)Cy}(CNCy)] (5) in good (72-83%) isolated yields. Complexes 4 and 5 were characterized by elemental analyses (C, H, N), HR ESI(+)-MS, IR...
متن کاملMetal-catalyzed semiconductor nanowires
Semiconductor nanowires have become an important building block for nanotechnology. The growth of semiconductor nanowires using a metal catalyst via the vapor–liquid–solid (VLS) or vapor–solid–solid (VSS) mechanism has yielded growth directions in 〈1 1 1〉, 〈1 0 0〉 and 〈1 1 0〉 etc. In this paper, we summarize and discuss a broad range of factors that affect the growth direction of VLS or VSS gro...
متن کاملThe Base Catalyzed Rearrangement Of
Fortimicins A (1) and B (2) are aminoglycoside antibiotics. Both compounds consist of a 6-epipurpurosamine B moiety and the aminocyclitol fortamine. Fortimicin A differs from B in having a glycyl substituent at its 4-N-position. Base catalyzed loss of glycine from the 4-amino group of 1 to give 2 and a rearrangement product, 2'-N-glycylfortimicin B or isofortimicin (3), has been reported by TAD...
