摘要:一套NMR技术揭示了cavitand(1)与一系列单不饱和脂肪羧酸及其相应的甲酯形成2:1宿主-客体复合物.所有的羧酸盐都以j形基序与胶囊结合,羧酸盐位于二聚体的赤道区域,并且链的反向连接和主体每个极性区域的甲基末端.来宾交换在NMR时标上很慢,而翻滚则慢或接近NMR时标,具体取决于双键的位置和立体化学.相反,根据双键的位置和立体化学,发现甲酯以三个基序结合.因此,观测到这些酯结合成j形,U形(来宾中的转弯占据一个极性区域,而两个末端争夺另一个极的占据),或反向的j形主题(酯部分和每个部分分别占据一个极点和位于赤道附近的甲基末端).相对结合常数(k Rel的测定表明对胶囊的亲和力取决于双键的位置和立体化学.

摘要:Provided are a solid catalyst which gives a cyclic carbonate at a high yield and a high selectivity, which is stable and which may be readily separated after reaction; and a method of industrially advantageous, inexpensive and safe production of a cyclic carbonate by the use of the catalyst. The catalyst contains an inorganic solid substance having a surface modified with an ionic substance containing a Group 15 element; or contains an ionic substance containing a Group 15 element, and an inorganic solid substance. The modifying group for surface modification of an inorganic solid substance is an ionic substance containing a Group 15 element. The ionic substance containing a Group 15 element is at least one substance selected from organic phosphonium salts, organic ammonium salts, organic arsonium salts and organic antimonium salts.
