Abstract

Complexes of formula [(HNO)TiCl] and [(HNO)Ti(OPr)] (HNOH = HOPh'CHNH(CH)NHCHPh'OH, where Ph' = 2,4-(CMePh)CH) were synthesized by the reaction of the salan ligand precursor HNOH with TiCl and Ti(OPr), respectively, in high yields. The dichlorido complex [(HNO)TiCl] revealed to be an efficient catalyst for the reduction of benzaldehyde in toluene. Full conversion was observed after 24 h at 55 °C in THF. The same catalyst also converted phenylacetaldehyde and hydrocinnamaldehyde into the corresponding alkanes quantitatively.

摘要

通过salan配体前体HNOH（其中Ph' = 2,4-(CMePh)CH）分别与TiCl₄和Ti(OPr)₄反应，高产率地合成了式为[(HNO)TiCl₂]和[(HNO)Ti(OPr)₂]的配合物。二氯配合物[(HNO)TiCl₂]被证明是甲苯中苯甲醛还原反应的有效催化剂。在55℃的四氢呋喃中反应24小时后观察到完全转化。相同的催化剂还能将苯乙醛和氢化肉桂醛定量地转化为相应的烷烃。
