4-[B(OH)2]-1,2-C6H3(CHO)2 have been prepared and their specific behavior in solution under various conditions has been investigated using NMR spectroscopy. The former compound undergoes a ring-chain tautomeric rearrangement to form a cyclic structure of 1,3-dihydro-1,3-dihydroxy-4-formylbenzo[c][2,1]oxaborole predominating in acetone-d6 solution and characterized by X-ray diffraction.
制备了两种异构的硼化邻苯二甲醛3-和4- [B(OH)2 ] -1,2-C 6 H 3(CHO)2,并使用NMR光谱研究了它们在各种条件下在溶液中的比行为。前一种化合物发生环链互变异构重排,形成在丙酮d 6溶液中占主导地位的1,3-二氢-1,3-二羟基-4-甲酰基苯并[c] [2,1]恶硼硼烷的环状结构,其特征在于X射线衍射。
