  The present invention includes methods for preparing resveratrol, resveratrol esters and substituted and unsubstituted stilbenes of the formula given below; where each Y is —O or halogen, each Z is —O or halogen, each n and each m is independently the value of 0, 1, 2, 3, 4 or 5, each A and each B is independently selected from P n , R or absent, each V and each W is independently selected from P n , straight or branched alkyl of from (2) to (6) carbon atoms and cycloalkyl of from (3) to (8) carbon atoms, alkoxy, phenyl, benzyl or halogen, R is independently selected from the group comprising alkyl with at least one carbon atom, aryl and aralkyl, P n is an alcohol protecting group and diastereoisomers of the foregoing. The compounds are made from a multi-step process including a N-heterocyclic carbon-type ligand coupling in the presence of a base with benzyol halide and styrene coupling partners. These compounds show increased stability for use in the food, cosmetic and pharmaceutical industries.

  本发明涉及一种制备白藜芦醇、白藜芦醇酯和给定以下结构式的取代和未取代的stilbenes的方法；其中每个Y是—O或卤素，每个Z是—O或卤素，每个n和每个m独立地取值为0、1、2、3、4或5，每个A和每个B独立地从Pn、R或缺席中选择，每个V和每个W独立地从Pn、由（2）到（6）个碳原子的直链或支链烷基和由（3）到（8）个碳原子的环烷基、烷氧基、苯基、苄基或卤素中选择，R独立地从包括至少一个碳原子的烷基、芳基和芳基烷基的群体中选择，Pn是醇保护基和上述化合物的对映异构体。这些化合物是通过多步过程制备的，其中包括在碱存在下与苄基卤和苯乙烯偶联合成N-杂环碳型配体偶联。这些化合物在食品、化妆品和制药行业中显示出增强的稳定性。

  Fluoroelastomers based on vinylidene fluoride and containing small quantities of bromided or iodided olefine as a comonomer in function of vulcanization place, are admixed with perfluoropolyethers or polycondensation derivatives thereof, in quantities of 1 - 25% by weight on the elastomer: the thus obtained mixture being co-vulcanizable with organic peroxides. More particularly, there are used perfluoropolyethers obtained by polycondensation of e.g. a diamine with a polyoxaperfluoroalkandioc acid containing repetitive structural units -CF20- and -CF2CF20- , in a number not inferior to 5.

  以偏氟乙烯为基础、含有少量溴化或碘化烯烃作为共聚单体的含氟弹性体，在硫化过程中可掺入全氟聚醚或其缩聚衍生物，掺量为弹性体重量的 1 - 25%，由此得到的混合物可与有机过氧化物共同硫化。 更具体地说，可使用全氟聚醚，全氟聚醚是由二胺与含有重复结构单元 -CF20- 和 -CF2CF20- 的聚氧乙烯-氟烷二酸缩聚而成，其数量不低于 5。
