摘要:制备了两种[[nhc] Au I-ar]的同源络合物,其中的芳基取代基为苯基或五氟苯基.用phicl 2处理[(ipr)au I C 6 F 5 ]会直接产生预期的au Iii氧化加成产物[(ipr)au Iii(cl)2 C 6 F 5 ].该配合物是热稳定的,但经过光化学还原消除后可生成[(ipr)au I Cl]和c 6 F 5 Cl.相反,[(ipr)au I Ph]与phicl 2的反应不会提供可分离的au Iii氧化加成产物,而是直接导致[[(ipr)au I Cl]和phcl的形成,大概是通过[(ipr)au Iii(cl)2 Ph]中间体.这些相关的反应途径是根据两种[(nhc)au I-ar]配合物的电子结构合理化的.

摘要:A method for the production of poly(vinyl trifluoroacetate) and copolymers thereof with vinyl esters is described. Poly(vinyl trifluoroacetate) (PVTFA) is obtained in essentially quantitative yield under mild conditions by using non-chlorofluorocarbon solvents comprising siloxanes or perfluorinated fluid. Hexamethyl disiloxane is a particularly useful example of such solvents. Synthesis of syndiotactic PVTFA on a commercial scale without the use of environmentally-harmful solvents is made possible by the invention, which provides a convenient commercial route to syndiotactic polyvinyl alcohol.

标 题:Method for the synthesis and use of pentafluorophenyl lithium to produce tetrakis pentafluorophenyl borate
发明人：KRAFFT TERRY E
权利人:BOULDER SCIENT CO
摘要:Procedures are disclosed which preclude significant safety hazards in the production of bulk quantities pentafluorophenyl lithium. A pentafluorophenyl compound is reacted with an alkyl lithium compound in a reaction zone, preferably temperature controlled, under conditions such that only a small amount of a predetermined quantity of pentafluorophenyl lithium product is present in the reaction zone at any time. The product may be directly discharged from the reaction zone for combination with another reactant.
