Turning to C(sp 3 )-C(sp 2 ) and C(sp 3 )-C(sp) linkages, an array of viable coupling partners was identified to access broad regions of chemical space (Table ) . Alkenyl donors (bromides, iodides, and triflates), aryl halides (chlorides and bromides), and alkynyl bromides were all easily coupled with sulfonyl hydrazides (23-29, and 34; 17-22, and 33; 30-32 and 35, respectively) using similar conditions to that described above with the notable exception that the unique, but commercial, dNH2-bpy ligand often led to higher yields. Notably, unlike the majority of reductive modes of accomplishing such transformations, protodehalogenation and/or homodimerization of the sp 2 -halide substrate is greatly suppressed, thereby simplifying product isolation. The ability to utilize C(sp 2 )-chlorides and triflates is of great utility and the deletion of pyrophoric reagents (Negishi and Kumada type) , palladium, or redox-focused reaction setups (photo/electrochemistry) (3) will reduce the barrier to employing radical cross-couplings.
