Metallo-selective substitution reactions by amines or phosphines in HRuCo3(CO)12. 1H and 59Co N.m.r. studies of HRuCo3(CO)12–xLx(L = amines or phosphines, x= 0 to 2)
Abstract
The substitution of amines for the CO ligand of HRuCo3(CO)12 takes place preferentially at the ruthenium atom whereas the substitution of phosphines occurs exclusively at the cobalt atoms.
