Suzuki-type cross coupling between aryl halides and silylboranes for the syntheses of aryl silanes.
Herein we report Pd catalyzed Suzuki type cross coupling between aryl halides and silylboranes for the syntheses of aryl silanes. This reaction shows a general substrate scope, excellent compatibility with electrophilic functionalities and good yields.
متن کاملPalladium(II)-catalyzed Heck reaction of aryl halides and arylboronic acids with olefins under mild conditions
A series of general and selective Pd(II)-catalyzed Heck reactions were investigated under mild reaction conditions. The first protocol has been developed employing an imidazole-based secondary phosphine oxide (SPO) ligated palladium complex (6) as a precatalyst. The catalytic coupling of aryl halides and olefins led to the formation of the corresponding coupled products in excellent yields. A v...
متن کاملRhodium-catalysed cyclisation reaction of allenynes with arylboronic acids.
Allenynes having malonate-based tethers reacted with arylboronic acids in the presence of a rhodium(I) catalyst to sequentially form three carbon-carbon bonds, and arylated bicyclic skeletons were constructed in a stereoselective manner.
متن کاملCobalt‐Catalyzed Suzuki Biaryl Coupling of Aryl Halides
Readily accessed cobalt pre-catalysts with N-heterocyclic carbene ligands catalyze the Suzuki cross-coupling of aryl chlorides and bromides with alkyllithium-activated arylboronic pinacolate esters. Preliminary mechanistic studies indicate that the cobalt species is reduced to Co0 during the reaction.
متن کاملNickel-catalysed cross-coupling reaction of aryl(trialkyl)silanes with aryl chlorides and tosylates.
Using highly stable, readily accessible, and recyclable 2-(2-hydroxyprop-2-yl)cyclohexyl-substituted arylsilanes activated by a mild carbonate base, nickel-catalysed silicon-based aryl-aryl cross-coupling reaction proceeds for the first time with inexpensive aryl chlorides and tosylates in a highly chemoselective manner.
