  The present invention relates to a production process capable of selectively producing various kinds of carbonate compounds without restraint in high yields without using toxic compounds such as phosgene and crown ethers, without producing corrosive gases such as hydrogen chloride as a by-product, and without necessity of removing the chloroform as a by-product by distillation, and to a method for producing a carbonate compound, containing reacting compound (1) with a compound having an OH group in the presence of a metal salt and 0.2 to 4.0 mol of compound (2) per mol of the metal salt to obtain a carbonate compound, in which m is an integer of 1-10, Q is an alkylene group having 1 to 4 carbon atoms, etc, and R 10 and R 11 are alkyl groups having 1 to 5 carbon atoms, etc.

  We recorded high-resolution solid-state 13C NMR spectra of ethylene oxide oligomers, cryptands, and crown ethers complexed with metal ions, determined by cross polarization-magic angle spinning (CP-MAS) NMR method. It is found that peak-intensities of these complexes are significantly enhanced by the presence of metal ions which act toward conformational fixation of flexible ligand molecules. The 13C

  我们记录了与金属离子络合的环氧乙烷低聚物、穴状配体和冠醚的高分辨率固态 13C NMR 光谱，通过交叉极化魔角旋转 (CP-MAS) NMR 方法确定。发现这些复合物的峰强度因金属离子的存在而显着增强，金属离子对柔性配体分子的构象固定起作用。作为冠醚开链类似物与 HgCl2 或 CdCl2 复合的环氧乙烷低聚物的 13C 化学位移与附近单键的一对扭转角成功相关。13C 环状离子载体的化学位移与配体分子的构象变化一起被置换（高达 6 ppm）。此外，与穴状配体的氮原子相邻的碳的 13C 化学位移 [2.2.2] 和 [2.2。1] 与近键的一对扭转角密切相关。此外，我们发现几种金属配合物与双环己基的顺-顺-顺和顺-反-顺异构体...
