摘要: Abstract In the 2,3-dihalogen-1,3-diphenylpropan-1-one series for four diastereomeric pairs with different halogens, use of dipole moment in conjunction NMR data positively identifies configuration predominant rotamer. all cases both erythro and threo exist conformation antiperiplanar protons. The differences between spectra diastereomers are discussed.
