摘要: 本文利用1HNMR法研究棉酚及其胺类衍生物(双苯胺棉酚,双丁基棉酚和双嘧啶棉酚)在不同溶剂(CDCl3,DMSO-d6,C6D6,CD3COCD3,DMF-d7等)中和不同的酸碱环境下的氢转移(即结构互交).实验表明,棉酚、双苯胺棉酚、双丁基棉酚和双嘧啶存在着三种不同的异构体.这些异构体在同一溶剂不同环境下可以并存或者相互转变.

Abstract: In this paper, the hydrogen transfer of gossypol and its imino derivatives (dianilinogossypol, dipyrimidinyliminogossypol and di-n-butyliminogossypol) in various solvents (CDCl3,DMSO-d6,C6D6,CD3COCD3 and DMF-d7) under different acidic or basic conditions was shudicd by 1H NMR method. Results show that, three different tautomers existed for each of the above mentioned gossypol imino derivatives, Moreover, the forms of these three tautomcrs are interchangable or co-exist in the same solvent under different conditions.
