Saturated aldehydes and ketones are converted via their p-toluenesulfonyl hydrazones to the corresponding alkanes using dichloro bis(1,4-diazabicydo[2.2.2]octane)(tetrahydroborato) zirconium(IV) (ZrBDC). The reactions were performed in DMF-sulfolane at 110 °C and gave the corresponding alkanes in high yields. Regioselectivity in the reduction of α,β-unsaturated carbonyl groups was also observed.
使用二氯双(1,4-二氮杂双环[2.2.2]辛烷)(四氢硼酸)锆(IV) (ZrBDC),饱和醛和酮通过它们的对甲苯磺酰腙转化为相应的烷烃。该反应在 DMF-环丁砜中于 110°C 下进行,并以高产率得到相应的烷烃。还观察到 α,β-不饱和羰基还原的区域选择性。
