A simple three-step, high-yield synthesis of the titled azides from Mn2(CO)10 and P-P is described involving the intermediate aqua complexes, fac-[Mn(CO)3(P-P)(H2O)]BF4, 3a,b. The aqua ligand is very labile; it is easily exchanged for D2O, PPh3, and NO2−. Crystal structures of the two titled aqua complexes and fac-[Mn(CO)3(depe)(PPh3)]BF4, 6a, are reported. The aqua complexes react instantaneously with aqueous NaN3 to give quantitative yields of the corresponding covalent azides which undergo the expected 1,3-dipolar additions with CF3CN to give the corresponding tetrazoles whose crystal structures are also reported.
