Studies based on polarographic reduction potentials, electronic absorption spectra, and 1H and 13C nuclear magnetic relaxation data show that in solution the preferred conformation of formyl-1,4-benzoquinone is that with the formyl and quinonoid groups coplanar, and the formyl carbonyl group anti to the 1-carbonyl, whereas that of acetyl- and pivaloyl-1,4-benzoquinone has the acyl groups approximately
基于极谱还原电势,电子吸收光谱以及1 H和13 C核磁弛豫数据的研究表明,在溶液中,甲酰基-1,4-苯醌的最佳构型是甲酰基和醌型基团共平面,甲酰基羰基对1-羰基抗的基团,而对乙酰基和新戊-1,4-苯醌的基团具有近似垂直于醌环的酰基。
