Nickel-Catalyzed Sonogashira C(sp)-C(sp2) Coupling through Visible-Light Sensitization

An efficient method for visible-light-initiated, nickel-catalyzed Sonogashira C(sp)-C(sp2) coupling has been developed via an energy-transfer mode. Thioxanthen-9-one as a photosensitizer could significantly accelerate the arylation of alkynes with a wide

Gold(l)-catalyzed ring expansions of unactivated alkynylcyclopropanes to (E)-2-alkylidenecyclobutanamines in the presence of sulfonamides

(Chemical Equation Presented) The ring expansion of cyclopropane derivatives provides a powerful method to construct synthetically useful four-membered carbocycles. Herein, a new type of gold(l)-catalyzed ring expansion of an unactivated alkynylcyclopropane/sulfonamide trapping strategy to (E)-2-alkylidenecyclobutanamines was described. The reaction tolerates a range of aryl and alkyl substituents with moderate to good yields.
