Reduction of 1,1,1-trihaloalkanes by Cr(II) or Cr(III) regenerated by Fe(0) in moist tetrahydrofuran at room temperature stereoselectively generates (Z)-1-halo-1-alkenes and (Z)-1-halo-2-alkoxy-1-alkenes in good to excellent yields.
在室温下,湿润的
四氢呋喃中,通过Fe(0)再生Cr(II)或Cr(III)还原1,1,1-三卤代
烷烃,能立体选择性地以良好至优异的产率生成(Z)-1-卤-1-烯烃和(Z)-1-卤-2-烷氧基-1-烯烃。
