Thus, iron nanoparticles stabilized by 1,6-bis(diphenylphosphino)hexane or polyethylene glycol exhibit high activity for the crosscoupling of aryl Grignard reagents with primary and secondary alkyl halides bearing b-hydrogen atoms. This catalyst has also proven to be effective in a tandem ring-closing/crosscoupling reaction. Magnetically separable mesoporous carbons constructed from mesocellular carbon and Fe/Fe3O4 core-shell ferromagnetic nanoparticles ×¢Ò⣺ǰºóÁ½¾äûÓйØÏµ£¬ºóÃæÒ»¾äÖ»ÊÇÒ»¸ö¸´ÔÓµÄÖ÷Óï [ Last edited by fxhzfmcg on 2009-9-16 at 16:59 ] |
