    Abstract: The invention concerns an organometallic compound of formula RO-M(L1)X (L2)Y (L3)Z wherein M is a metal selected from titanium, zirconium, hafnium, iron (III), cobalt (III) or aluminium; L1 and L2 are each independently selected from a diketonate, an ester or amide of acetoacetic acid, a hydroxycarboxylic acid or ester thereof, R1COO- where R1 is substituted or unsubstituted C5 - C30 branched or linear alkyl, substituted or unsubstituted aryl including polycyclic structures such as naphthyl or anthracyl, phosphate, phosphinate, phosphonate, siloxy or sulphonato, provided that when L1 is a ligand which forms two covalent bonds with the metal atom, and x= 1 then y = 0; L3 is selected from substituted or unsubstituted aryloxy, R2COO- where R2 is a linear or branched C6 - C30 alkyl or a substituted or unsubstituted aryl, a polyoxyalkyl or hydroxyalkoxyalkylgroup; R is alkyl or hydroxy-alkyl hydroxyalkoxyalkyl, or (hydroxy)polyoxyalkyl group, x, y and z are each either 0 or 1 (x+y+z ) ≤ V-1, where V= the valency of the metal M. The invention further concerns compositions and processes for the manufacture of polyurethane articles using the organometallic compounds as catalysts to provide cured articles having a comparable performance to those produced using a commercial mercury-based catalyst.
