An air-stable hypervalent organoantimony (III) triflate complex (PhN(CH2C6H4)2SbOSO2CF3) having intramolecular N → Sb coordination was synthesized and characterized by techniques such as 1H NMR, 13C NMR, TG-DSC, X-ray diffraction and elemental analysis. The complex shows relatively strong Lewis acidity (0.8 < Ho ≤ 3.3). It exhibits excellent catalytic performance towards the allylation of aldehydes
合成了一种具有分子内N→Sb配位的空气稳定的高价有机三价铁锑(III)复合物(PhN(CH 2 C 6 H 4)2 SbOSO 2 CF 3),并通过诸如1 H NMR,13 C NMR,TG等技术进行了表征-DSC,X射线衍射和元素分析。的复杂的表演相对强的路易斯酸性(0.8 < ħ ö ≤3.3)。在室温下,它对醛与四烯丙基化的烯丙基化表现出优异的催化性能,并显示出良好的热稳定性和可回收性。该催化体系使得能够方便且有效地合成均烯丙基醇。
