The Synthesis, Spectral, and Electrochemical Characterization of Novel Alkoxybenzoquinone Derivatives

The novel monosubstituted benzoquinone compounds 3e , 3g , 3h ; 2,5‐ O ‐ substituted benzoquinone compounds 4a , 4b , 4c , 4d , 4e 4g and known compound 4h and 2,6‐ O ‐ substituted benzoquinone compounds 5e , 5f , 5g , 5h were obtained by the reaction of p ‐chloranil ( 1 ) and related alcohol compounds in potassium carbonate (K 2 CO 3 ) solution of acetonitrile or chloroform with Et 3 N. The novel cyclic compounds 7 , 8 and 10 , 11 were obtained from the reaction of p ‐chloranil ( 1 ) and diols in potassium carbonate (K 2 CO 3 ) solution of acetonitrile at room temperature. The structures of novel compounds were characterized by using micro analysis, FT‐IR, 1 H‐NMR, 13 C‐NMR, MS and cyclic voltammetry.
