Rhodium-catalyzed C-H allylation of acrylamides with allyl acetates is reported. The use of weakly coordinating directing group resulted in high reaction efficiency, broad functionality tolerance and excellent γ-selectivity, which opens a new synthetic pathway for the access of 1,4-diene skeletons.

The Rh(III)-catalyzed C-H alkynylation of acrylamide derivative is realized using a hypervalent alkynyl iodine reagent. The use of a weakly coordinating directing group proved to be of critical importance. This reaction displays broad functional group tolerance and high efficiency, which opens a new synthetic pathway to access functionalized 1,3-enyne skeletons.

supporting information, p. 10809 - 10813 (2013/09/02)
Photocatalyzed reduction of diaryliodonium salts was achieved by using [Cu(dpp)2][PF6] as a photoactive complex and DIPEA as a reductive quench. The application of a copper catalyst allows the generation of aryl radicals under mild conditions and maintains their reactivity for C-C bond formation processes.

One-pot chemoselective functionalization of arylsilanes via cascade metal-metal exchange reactions
Hupe, Eike,Calaza, M. Isabel,Knochel, Paul
, p. 1390 - 1391 (2007/10/03)
A cascade-transmetallation sequence allows a one-pot conversion of arylsilanes into functionalized arylcoppers; they react with various types of electrophiles (allylic halides, acid chlorides, bromoalkynes); bimetallic zinc-copper-reagents can be prepared by this method either directly or in a sequential fashion.
