Metal-free Oxidative Cross-Coupling Reaction of Aromatic Compounds Containing Heteroatoms

21.06.2017 | Koji Morimoto; Toshifumi Dohi; Yasuyuki Kita, Synlett, 2017

SynlettDOI: 10.1055/s-0036-1588455 The biaryl unit containing a heteroatom is a key structure in a large number of natural products and π-conjugated organic systems. The cross-couplings can provide powerful methods for the construction of biaryls and heterobiaryls; thus the development of a new ...
