摘要: The NMR, IR, and UV spectra of some α-keto phosphorus compounds, (C2H5)2PCOR, (C2H5)2P(S)COR, [(C2H5)2CH3PCOR]+I− (R=C6H5 CH3), were measured. carbonyl stretching frequency the n-π* transition show considerable red shifts, but shifts are smaller than those organosilicon compounds. lowering π* level, which resulted from interaction with a vacant d orbital atom, was found to be largely responsible for shift in particularly [(C2H5)2CH3PCOR]+I−. rise n level group rather small.
