WebOct 26, 2010 · This paper describes the first direct approach to alkenyl nitriles from allylarenes or alkenes facilitated by an inexpensive homogeneous iron catalyst. Three C−H bond cleavages occur under the mild conditions during this process. Mechanistic studies indicate that the cleavage of the allyl C(sp3)−H bond is involved in the rate-determining …

WebCsp3-CF 3 bond-forming reductive elimination. Although aryl-CF3 bond-forming reductive elimination has been studied on PdII/IV, Ni III and Au complexes,4, 52-55 Csp3-CF 3 bond-forming reductive elimination from any transition metal complexes with well-defined structures remains essentially unknown. Toste has recently reported a formal Csp3-CF WebHowever, organocopper(III) complexes with well-defined structures that can undergo reductive elimination are extremely rare, especially for the formation of Csp 3 –Csp 3 bonds. We report herein a general method for the synthesis of a series of [alkyl-Cu III -(CF 3 ) 3 ] − complexes, the structures of which have been unequivocally ...
