A procedure for the synthesis of tertiary amines via reductiveamination of aldehydes with molecular hydrogen as a reducing agent using homogeneous rhodium catalysis is presented. Using an amine to aldehyde ratio of 4/1 enabled the synthesis of tertiary amines from nine different aldehydes and nine different secondary amines with selectivities up to 99% and turnover frequencies (TOF) up to 7200 h−1
提出了一种使用均相铑催化通过分子氢作为还原剂对醛类进行还原胺化反应合成叔胺的方法。使用胺/醛比率为4/1时,可以由9种不同的醛和9种不同的仲胺合成叔胺,其选择性高达99%,周转频率(TOF)高达7200 h -1... 反应显示出对醇和酯功能的高耐受性,从而允许形成多功能分子。另外,仲胺也可以通过该合成来制备。对于所有化合物,活性都是通过吸收氢气来确定的。为了增加该过程的可持续性和效率,已经成功地制定了剂量策略。使用确定的反应指标,可以化学计量使用醛和胺,而不会显着降低选择性。
