Abstract

Thermolysis of [(MoO(S2CNEt2)(mu-NPh)}2] in the presence of an excess of phenyl isocyanate affords the ureato complex [Mo2(NPh)2(S2CNEt2)2(mu-NPh){mu-PhNC(O)NPh}] 1 as a result of oxo substitution, and insertion of an isocyanate into one of the bridging imido functionalities; heating 1 in toluene results in release of phenyl isocyanate to give the tetraimido complex [{Mo(NPh)(S2CNEt2)(mu-NPh)}2] 2, a process which is reversible.
