Transition metal catalyzed synthesis of aryl sulfides.
The presence of aryl sulfides in biologically active compounds has resulted in the development of new methods to form carbon-sulfur bonds. The synthesis of aryl sulfides via metal catalysis has significantly increased in recent years. Historically, thiolates and sulfides have been thought to plague catalyst activity in the presence of transition metals. Indeed, strong coordination of thiolates ...
متن کاملA mild and facile synthesis of aryl and alkenyl sulfides via copper-catalyzed deborylthiolation of organoborons with thiosulfonates.
An efficient deborylthiolation of aryl- and alkenylborons with thiosulfonates has been achieved under mild conditions using a copper catalyst. All steps of the experimental process were free from unpleasant odors. The mild reaction conditions as well as ready availability of boron compounds and thiosulfonates enabled easy access to an array of sulfides, including those bearing sensitive functio...
متن کاملNickel-catalyzed synthesis of aryl trifluoromethyl sulfides at room temperature.
Inexpensive nickel-bipyridine complexes were found to be active for the trifluoromethylthiolation of aryl iodides and aryl bromides at room temperature using the convenient [NMe(4)][SCF(3)] reagent.
متن کاملRuthenium-catalyzed transformation of alkenyl triflates to alkenyl halides.
In the presence of a ruthenium catalyst, alkenyl triflates were found to be transformed to the corresponding bromides, chlorides and iodides simply by treatment with a lithium halide (1.2 equiv.).
متن کاملEnantioselective protonation of alkenyl trifluoroacetates catalyzed by chiral tin methoxide.
Go catalytic! A catalytic enantioselective protonation of alkenyl trifluoroacetates was achieved by using an in situ generated chiral tin bromide methoxide as the chiral catalyst in the presence of methanol. Optically active ketones containing a tertiary stereogenic center at the α-position were obtained with enantioselectivities of up to 94 % ee.
