infrared spectra in the region of fundamental CO stretching vibrations in methylenchloride were measured for nine 1,3-bis-substituted-5,5-dimethylhydantoins. The arithmetic means of wave numbers of symmetric and antysymmetric CO stretching vibrations are correlated with Taft's inductive σ* substituent constants. The mechanism of the transmission of substituent effects in hydantoin systems is discussed.
摘要 对9种1,3-双-取代-5,5-二甲基乙内酰脲在二氯甲烷中基本CO伸缩振动区的红外光谱进行了测量。对称和反对称CO伸缩振动波数的算术平均值与Taft的电感σ*取代基常数相关。讨论了乙内酰脲系统中取代基效应的传递机制。
