Phosphorylacetic acid esters containing the menthoxy fragment at the phosphorus atom or at the carbonyl group were synthesized. The configurations of the enantiomerically pure compounds, viz., methyl (ethoxy)(menthyloxy)phosphorylacetate and menthyl [(2-chloro-ethoxy)(4-dimethylaminophenyl)phosphoryl]acetate, were established by X-ray diffraction and NMR spectroscopy.
合成了在磷原子或羰基上含有薄荷氧基片段的磷酸酯。通过 X 射线衍射和核磁共振光谱确定了对映体纯化合物的构型,即(乙氧基)(薄荷氧基)磷酰乙酸甲酯和[(2-氯-乙氧基)(4-二甲基氨基苯基)磷酰]乙酸薄荷酯。
Hydrosilylation of Carbonyl Compounds Catalyzed by Iridium(I) Complexes with (‐)‐Menthol‐Based Phosphorus(III) Ligands
New iridium(I) complexes with phosphorus(III) ligands based on naturally occurring (−)-menthol were synthesized and tested in the hydrosilylation of carbonyl compounds (ketones, aldehydes, esters). Catalytic systems provided great activity and chemoselectivity in the reduction of the carbonyl group showing high tolerance to many functional groups, also the unsaturated C−C double and triple bonds.
