[作者:VIVES GUILLAUME; KANG JUNGHO; KELLY KEVIN F; TOUR JAMES M,期刊:Organic Letters, 页码:5602-5605 , 文章类型: Article,,卷期:2009年11-24]
- The synthesis and imaging by scanning tunneling microscopy of a mixed wheeled nanovehicle composed of a p-carborane small-wheeled short front axle and a C-60 large-wheeled long rear axle that has been termed a nanodragst...
- Carbonyldiimidazole-Mediated Lossen Rearrangement
[作者:DUBE PASCAL; NATHEL NOAH F FINE; VETELINO MICHAEL; COUTURIER MICHEL; ABOUSSAFY CLAUDE LARRIVEE; PICHETTE SIMON; JORGENSEN MATTHEW L; HARDINK MARK,期刊:Organic Letters, 页码:5622-5625 , 文章类型: Article,,卷期:2009年11-24]
- Carbonyldiimidazole (CDI) was found to mediate the Lossen rearrangement of various hydroxamic acids to isocyanates. This process is experimentally simple and mild, with imidazole and CO2 being the sole stoichiometric byp...
