“…To date, a number of variations of the P–C couplings were developed comprising in situ formed catalysts from suitable precursors, such as Pd(OAc) 2 and PdCl 2 , and different added mono- or bidentate P-ligands. The protocol was extended to H -phosphinates, as well as secondary phosphine oxides applying a wide range of arenes [ 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 ]. Later on, Ni- and Cu complexes were also used as catalysts [ 10 , 11 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ].…”
