  铑催化的酰基转移反应中的平衡位移

  摘要：

  铑/膦配合物催化酰基氟，芳基酯，酰基膦硫化物和硫代酯之间的平衡酰基转移反应。使用合适的共底物来接受杂原子基团将平衡转移到所需的产物上。使用苯甲酰基五氟苯作为氟化物供体，将酰基膦硫化物和芳基酯转化为酰基氟，并使用（4-甲苯基硫代）五氟苯进行硫酯的氟化反应。分别使用二膦二硫化物和二硫化物/三苯基膦将酰氟转化为酰基膦硫化物和硫酯。在三苯基硅烷的存在下，由酰基氟和苯酚获得芳基酯。在铑配合物的存在下，芳基酯，酰基膦硫化物和硫代酯也可以相互转化。这些铑催化的酰基转移反应在中性条件下进行，无需使用酸或碱。羰基铑中间体参与这些反应是由硫代酯和炔烃的羰基硫化反应提示的。

  A cellulose acylate film produced by a melt-casting film formation, wherein the total of the number of projections having a height of from 0.1 μm to 100 μm and a length of at least 1 mm and the number of depressions having a depth of from 0.1 μm to 100 μm and a length of at least 1 mm is at most 10 per 10 cm of the width of the film. When built in a liquid-crystal display device, the cellulose acylate film significantly reduces the display blur in the device.
