邻叔丁基亚砜苄胺与2-乙烯基苯甲醛(或2-苯乙烯-苯甲醛)经缩合反应制得亚胺,再经硼氢化钠还原合成了两个新型的NH-叔丁亚砜-烯类三齿柔性配体(4a和4b),其结构经^1H NMR,^13C NMR和HR-MS表征。考察了4a或4b与Ir的络合物催化苯乙酮的转移氢化反应,转化率分别为94%和51%。
Two novel flexible tert-butylsulfinyl-NH-olefine tridentate ligands (4a, 4b) were synthesized by condensation and reduction starting with 2-tert-butylsulfinyl-benzylamine and 2-vinyl-benzaldehyde or 2-styrylphenyl-benzaldehyde. The structures were characterized by ^1H NMR,^13C NMR and HRMS. The catalytic activities of 4a and 4b with iridium in transfer hydrogenation reaction of acetophenone were investigated. The conversion were 94% and 51%, respectively.
