  • Ammonium-Salt-Tagged IMesAuCl Complexes and Their Application in Gold-Catalyzed Cycloisomerization Reactions in Water
    作者:Katrin Belger、Norbert Krause
    DOI:10.1002/ejoc.201403153
    日期:2015.1
    The total synthesis and characterization of ammonium-salt-tagged IMesAuCl complexes is described. Moreover, we have demonstrated their catalytic activity and recyclability in cycloisomerization reactions of allenic and acetylenic alcohols in water. The water-soluble gold catalysts can be stabilized by the addition of LiCl.

  • Tellurium/lithium exchange reactions in the synthesis of spiroketals and 1,6-dioxygenated systems
    作者:Alcindo A. Dos Santos、Jefferson L. Princival、João V. Comasseto、Simone M.G. de Barros、José E. Brainer Neto
    DOI:10.1016/j.tet.2007.03.178
    日期:2007.6
    O-dianions have been generated through concomitant acid/base and tellurium/lithium exchange reactions. The di-lithium salts were transmetallated with cerium chloride to the corresponding di-cerium salts and subsequently reacted with lactones and carboxylic acid anhydrides to yield the respective spiroketals. The di-lithium entities were also converted into the corresponding cyanocuprates that add in
    通过伴随的酸/碱和碲/锂交换反应生成了1,4-C,O-阴离子。用氯化铈将二锂盐金属转移成相应的二铈盐,然后与内酯和羧酸酐反应以产生相应的螺缩酮。二锂实体也被转化为相应的氰基丙酸酯,其将1,4-方式加成至2-环己烯-1-酮以形成1,6-二加氧化合物。
