The Pinner salt 2 derived from α-azidoacetonitrile by sequential treatment with triethylamine, triphenylphosphine and acyl chlorides or isothiocyanates was converted into the corresponding imidazole 5 or 6, respectively. The crystal structure of 6a has been determined by X-ray diffraction methods. Dimers of centrosymmetrically related molecules, linked by N-H...N bonds, join together to infinite chains through N-H...S=C halogen interactions.
通过三乙胺、三苯基膦和酰基氯化物或异硫氰酸酯的顺序处理,从δ-叠氮乙腈中得到的平纳盐 2 被分别转化为相应的咪唑 5 或 6。通过 X 射线衍射方法确定了 6a 的晶体结构。由 N-H...N 键连接的中心对称相关分子的二聚体通过 N-H...S=C 卤素相互作用连接成无限链。
