Abstract:

The preparation and characterization of four new compounds of the type CF32PENHCH3 and F2PENHCH3E O,S by aminolysis of the appropriate chlorophosphorus compound is described. Infrared and nmr spectra of the compounds indicate that no conformational preference is adopted on the latter time scale although the presence of conformational isomers may be indicated by infrared. Some hydrogen bonding is indicated by infrared studies especially for the compound F2PONHCH3, which appears to be strongly hydrogen bonded in all states. The nmr spectral behavior indicates the presence of coupling of the N-H proton to the methyl proton. Second-order intensity variations are observed when the N-H chemical shift is close to that of the CH3 group. The nmr spectra of the phosphines X2PNHCH3X F,CF3 show the same features. Author
