New Palladium Carbene Catalysts for the Heck Reaction of Aryl Chlorides in Ionic Liquids
摘要:
[GRAPHICS]The Heck reaction of aryl chlorides was investigated in the presence of defined monocarbenepalladium(0) complexes. Activated and nonactivated aryl chlorides provide the corresponding cinnamic esters and stilbenes in (Bu4NBr)-Bu-n as a ionic liquid in good to excellent yields.

The present disclosure describes a method of coupling a first compound to a second compound, the method comprising: providing the first compound having a fluorosulfonate substituent; providing the second compound comprising an alkene; and reacting the first compound and the second compound in a reaction mixture, the reaction mixture including a catalyst having at least one group 10 atom, the reaction mixture under conditions effective to couple the first compound to the second compound.
An object of the present invention is to provide a whitening agent containing a novel whitening substance as an effective ingredient. The above object is attained by providing a whitening agent containing equol and/or equol glycoside, in which one or more glycosyl groups bind to the hydroxyl group(s) of equol, as an effective ingredient.

Palladium salts such as Pd(OAc)(2) or PdCl2(PhCN)(2) in the presence of N,N-dimethylglycine (DMG) constitute the simplest and one of the most reactive and selective catalyst systems for the Heck reaction of aryl bromides with olefins known to date.
