  摘要：

  关于 Co2+、Ni2+、Zn2+、Cd2+、Cu2+、Pd2+ 和 Sn4+ 盐，1-异丙烯基取代的咪唑、2-甲基咪唑和吡唑分别表现为 N1 原子和 N2 原子上只有一个配位中心的单配位配体；1-异丙烯基吡唑在络合物形成条件下脱烷形成吡唑络合物。与盐酸反应后，1-异丙烯基咪唑中的不饱和取代基保持不变，并通过杂环的 N3 原子生成相应的氢氯化物。碱性最低的 1-异丙烯基吡唑也会通过烯基的双键吸收 HCl。

  摘要：

  A number of previously unknown N-isopropenyl-substituted pyrroles, indoles, and di- and -triazoles were synthesized in 20-86% yield by reaction of the corresponding azole with an equilibrium mixture of propyne with allene or pure propyne and allene in the system KOH-DMSO (105-145degreesC, 5-15 h, atmospheric or elevated pressure). The reaction is regioselective. The electronic and steric structure and the degree of conjugation between the exocyclic double bond and the azole ring are discussed on the basis of the H-1 and C-13 NMR spectra. Almost complete absence of p-pi conjugation in alpha,alpha'-disubstitutecl N-isopropenylazoles have been found.
