Notes:
Additive shielding parameters for the phenylseleno group (ZPhSe-gem = 1.36; ZPhSe-cis = 0.31; ZPhSe-trans = 0.29) have been estimated. Examples of the calculation of chemical shifts for olefinic protons in vinylic selenides by means of these increments are given. A comparison with 2-pyridylseleno and methylseleno substituents has been made. The standard deviations of the Z values are 0.06 for ZPhSe-gem, 0.10 for ZPhSe-cis and 0.05 for ZPhSe-trans.
