摘要:Methods for preparation of olefins, including 8- and 11-unsaturated monoenes and polyenes, via transition metathesis-based synthetic routes are described. Metathesis reactions in the methods are catalyzed by transition metal catalysts including tungsten-, molybdenum-, and ruthenium-based catalysts. The olefins include insect pheromones useful in a number of agricultural applications.

标 题:Process of use in perfluoroalkyation and reactant for making use of this process
发明人：ROQUES NICOLAS; RUSSEL JAMES
权利人:RHODIA CHIMIE SA
摘要:The subject-matter of the present invention is a process of use in perfluoroalkylation and a reactant for making use of this process. This process is defined in that it comprises a stage in which a material of formula RfH and a base (or a species capable of generating a base) are brought into contact, in a polar and anhydrous medium, with a substrate carrying at least one electrophilic functional group. Application to organic synthesis.
