                                    From the chemical shifts of the meta- and para-carbon atoms of the phenyl group in phenylquinazolines the sigma-I and sigma-R0 constants of 2- and 4-quinazolinyl groups were determined. Correlation equations which enable us to calculate the sigma-constants of various substituted 2- and 4-quinazolinyl groups are proposed.
