Tetraalkyl analogs of DIOP, (−)-EtDIOP, (−)-i-PrDIOP, and (−)-CyDIOP, have been prepared for the first time by the reaction of (+)-2,3-O-isopropylidene-2, 3-dihydroxy-1,4-difluorobutane and the corresponding lithium dialkylphosphides. These diphosphines form cationic Rh(I) complexes, [Rh(-)-RDIOP} (NBD)]C104 (R=Et, i-Pr, and Cy), which show remarkable reactivity toward dihydrogen
通过 (+)-2,3-O-异亚丙基-2,3-二羟基-1,4-二氟丁烷和相应的二烷基膦锂反应,首次制备出了 DIOP 的四烷基类似物 (-)-EtDIOP、(-)-i-PrDIOP 和 (-)-CyDIOP。这些二膦形成了阳离子 Rh(I) 复合物 [Rh(-)-RDIOP} (NBD)]C104(R=Et、i-Pr 和 Cy),它们对二氢
