  日期：——

  A palladium-catalyzed dicarbonylation of p-benzoquinones with aryl triflates has been developed. Using Cr(CO)6 as the CO source, the reaction proceeds smoothly and efficiently to give a series of aryl esters in moderate to good yields (up to 90%).

  已经开发了对苯醌与芳基三氟甲磺酸酯的钯催化二羰基化反应。使用 Cr(CO) 6作为 CO 源，该反应顺利且高效地进行，以中等至良好的收率（高达 90%）得到一系列芳基酯。

  This invention relates to flexible structures ( 401 ) that respond to the application of an agent. Upon application of the agent, the flexible structure bends ( 402 ) in a predetermined fashion. The flexible structure is formed from a polymer liquid crystal that is orientated to define an upper surface layer and a lower surface layer having an essentially different molecule orientation, and the polymer liquid crystal is such that a length/width ration is changed upon application of the agent. Thereby, the upper and lower surface layers respond differently to the application of the agent, resulting in bending or un-bending of the flexible structure ( 401 ).
