摘要：

The O-17 NMR chemical shift data for a series of substituted 10-methyleneanthrones and related 10-alkylanthrones in acetonitrile solution at 75-degrees-C are reported. The O-17 NMR chemical shift value of 10-methyleanthrone 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 O-17 NMR chemical shifts of the 10-substituted methyleneanthrones with sigma+ constants is noted.
