Abstract
Substituent chemical shift (scs) values for the acetylation and mesylation of hydroxy-p-benzoquinones and for the introduction of acetyloxy and mesylo xy groups into p-benzoquinones were derived after complete C-13 NMR assignm ent of all ring carbons for nine perezone derivatives and six thymoquinone derivatives, which follow from one-bond and long-range multiplicities.
