January 19, 2007Objective: Determination of absolute structures of various β,β-dihaloenones by means of X-ray diffraction. Methods: Synthesis of various β,β-dihaloenones by means of iodonium induced rearrangements and X-ray diffraction experiments for absolute structures Results: Syntheses of (Z)-4-bromo-4-iodo-3-phenyl-3-buten-2-one, 2-[(Z) bromoiodomethylidene] cyclohexanone, (Z)-10-(Bromoiodoemethylidene) phenanthren-9(10H)-one and 2-[(Z)-bromoiodomethylidene]-1,8,8- trimethylbicyclo[3.2.1]octan-3-one accomplished.engMahidol Universityβ,β - dihaloenoneStereoselectivityGeometryHypervalent iodineProceeding Book
