Very strong trans effect in ruthenacyclic carbamoyl complexes leads to ligand redistribution in phosphine derivatives

Very strong trans effect in ruthenacyclic carbamoyl complexes leads to ligand redistribution in phosphine derivatives

The ruthenacyclic carbamoyl complexes [Ru (2-NHC(O)C5H4N) (CO)2(X) (NCMe)] (X = Cl, Br) (1) and [Ru (2-NHC(O)C5H4N) (CO)2 (2-S-Py)] (2) undergo substitution reactions with organophosphines to afford derivatives which are prone to a redistribution of the phosphine ligand. We have studied these redist...
