What is Natural abundance ^17^O NMR spectroscopic study of quinone methides about?
## Abstract The ^17^O NMR chemical shift data for a series of substituted 10‐methyleneanthrones and related 10‐alkylanthrones in acetonitrile solution at 75°C are reported. The ^17^O NMR chemical shift value of 10‐methyleneanthrone is shielded by __ca__. 35 ppm compared with that of anthraquinone. The chemical shifts of the 10‐methyleneanthrones range from 493 ppm for 10‐bromomethyleneanthrone to 440 ppm for 10‐diethylaminomethyleneanthrone. A correlation of the ^17^O NMR chemical shifts of the 10‐substituted methyleneanthrones with σ^+^ constants is noted.
