| Abstract: | Abstract The syntheses of 16 phenyl- (1 and 3) and phenylthiophosphoryl (2) derivatives are described. The 13C and 17O NMR data sensitively reflect electron density changes in the phosphoryl substituents caused by pπ–dπ back-donation from X/Y to P. Taft constants σ1 and σR 0 were derived for 16 phosphoryl substituents. |
