oxidation of olefins into ketones. The reaction is catalyzed by the hexadecafluorinated iron–phthalocyanine complex FePcF16 with stoichiometric amounts of triethylsilane as an additive under oxygen atmosphere to give ketones in good to high yields with excellent chemoselectivity and functional group tolerance. Ketone formation proceeds in up to 95 % yield and with 100 % regioselectivity while the corresponding

The substrate scope in the dynamickineticresolution of secondary alcohols was studied by using 31 structurally different alcohols and isopropenyl acetate in the presence of dicarbonylchlorido(pentabenzylcyclopentadienyl)ruthenium and Candida antarctica lipase B (Novozym435, CAL-B) in toluene. The enzyme and the rutheniumcomplex were shown to function in a highly compatible manner allowing the conversion
A new series of chiral bimetallic Lewisacids, 5,5′-bis[(R)-2-aryl-1,3,2-dioxaborolan-4-one], have been prepared from L-(+)-tartaric acid and arylboronic acids. In the presence of these Lewisacids, unsymmetric ketones were reduced quantitatively by LiBH4, in moderate to good ee’s (up to 99% ee). The counter cation of BH4− significantly affects the ee’s of the products. The reaction is applicable to
一系列新的手性双金属路易斯酸,5,5'-bis[(R)-2-aryl-1,3,2-dioxaborolan-4-one],已从 L-(+)-酒石酸和芳基硼酸。在这些路易斯酸的存在下,不对称酮被 Li 以中等至良好的 ee(高达 99% ee)定量还原。BH4- 的抗衡阳离子显着影响产品的ee。该反应适用于芳基烷基酮、二烷基酮和二芳基酮。
