Willis Pyridinates for Palladium-Catalyzed Cross-Coupling Reactions
Description: Professor Willis and partners at Pfizer have shown with pyridine-2- sulfinates a palladium-catalyzed desulfinylative cross-coupling process can be realized.
Organosilanols
Over the past several years, the Pd-catalyzed cross-coupling of silicon compounds (Hiyama coupling) has rapidly gained acceptance as a suitable alternative to more commonly used methods such as Stille (Sn), Kumada (Mg), Suzuki (B), and Negishi cross-couplings (Zn).
Imidazolium Derived Reagents
N-Acylimidazoles were recognized in the early 1950s as reactive intermediates suitable for the acylation of amino compounds. The search for better coupling reagents than DCC led to the development of CDI (1,1’-carbonyldiimidazole) and related carbonylimidazoles.
Functionalized Alkynes
Alkynes contain a highly versatile functional group that may be utilized for numerous reactions such as electrophilic additions of hydrogen, halogens, hydrogen halides, or water; metathesis; hydroboration; oxidative cleavage; C–C coupling; and cycloadditions
