Efficient routes toward activation of gem-chlorofluorocyclopropane-derived (2-fluoroallyl)boronates for allylboration of various ketones including functionalized and low-reactive ones were developed. Increasing the B electrophilicity by the transformation of a boronate moiety into a borinic ester with BuLi/trifluoroacetic anhydride (TFAA) makes (2-fluoroallyl)boration of acetyl arenes/hetarenes and aliphatic ketones possible with high diastereoselectivity. For low-reactive or sterically hindered ketones (e.g., benzophenone, adamantanone), CuF-based catalysts were developed: (NHC)CuF·HF and (NHC)CuOTf in the presence of an excess of KHF2 (NHC = IPr, SIPr, IPrCl). The experimental part of the paper was very detailed, including the reaction process of 4-Acetylpyridine(cas: 1122-54-9Category: pyridine-derivatives)
4-Acetylpyridine(cas: 1122-54-9) belongs to pyridine. Pyridines are often used as catalysts or reagents; particular notice has been paid recently to how pyridine coordinates to metal centers enabling a wide range of valuable reactions. Category: pyridine-derivatives
