WebAug 13, 2024 · A new Csp 3 –Csp bond forming reaction is reported: the C=N bond of widespread imines reacts with acetylene gas in the presence of superbase KOtBu/DMSO at room temperature to afford terminal α-aminoacetylenes in up to 94 % yield. The reaction allows nitrogen heterocycles, e.g. 3H-indoles, to be directly cross-coupled with acetylene … 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
