| Abstract: | The 1H, 13C and 77Se chemical shifts and the 1JC(Me)H(Me)], 1.2J(SeC) and 2J(SeH) coupling constants in 14 para- or meta-substituted selenoanisoles, R? C6H4? Se? CH3, have been measured and the dependence of these parameters on the electronic effects of the substituent R is discussed. A significant (up to 6 ppm) deviation from additivity of the substituent influence on the shielding of the 13C ring carbons has been found. |
