Abstract:
The present invention relates to improved processes for the preparation of ruthenium or osmium complexes comprising P and N donor ligands, in particular, ruthenium complexes.

Claim (Index 1):
A process for preparing an [M(X) 2 (L 1 ) m (L 2 )] complex, the process comprising the step of:\n reacting an [M(X) 2 (L) 3 ] complex with a phosphorus ligand L 1  and a bidentate N,N ligand L 2  in a ketone solvent to form the [M(X) 2 (L 1 ) m (L 2 )] complex, wherein:\n M is ruthenium or osmium; \n X is an anionic ligand; \n L is a monodentate phosphorus ligand; \n L 1  is a chiral bidentate phosphorus ligand; \n m is 1; and \n L 2  is ligand (1), (2) or (3): \n wherein:\n R 31  and R 32 , R 43  and R 42 , and R 53  and R 52  are, independently, \u2014H, unsubstituted C 1-20 -alkyl, substituted C 1-20 -alkyl, unsubstituted C 3-20 -cycloalkyl, substituted C 3-20 -cycloalkyl, unsubstituted C 1-20 -alkoxy, substituted C 1-20 -alkoxy, unsubstituted C 5-20 -aryl, substituted C 5-20 -aryl, unsubstituted C 1-20 -heteroalkyl, substituted C 1-20 -heteroalkyl, unsubstituted C 2-20 -heterocycloalkyl, substituted C 2-20 -heterocycloalkyl, unsubstituted C 4-20 -heteroaryl or substituted C 4-20 -heteroaryl; \n R 33  and R 34 , R 43  and R 44 , and R 53  and R 54  are, independently, \u2014H, unsubstituted C 1-20 -alkyl, substituted C 1-20 -alkyl, unsubstituted C 3-20 -cycloalkyl, substituted C 3-20 -cycloalkyl, unsubstituted C 1-20 -alkoxy, substituted C 1-20 -alkoxy, unsubstituted C 5-20 -aryl, substituted C 5-20 -aryl, unsubstituted C 1-20 -heteroalkyl, substituted C 1-20 -heteroalkyl, unsubstituted C 2-20 -heterocycloalkyl, substituted C 2-20 -heterocycloalkyl, unsubstituted C 4-20 -heteroaryl or substituted C 4-20 -heteroaryl; \n R 35 , R 45 , R 46 , R 55 , R 56  and R 57  are, independently, \u2014H, unsubstituted C 1-20 -alkyl, substituted C 1-20 -alkyl, unsubstituted C 3-20 -cycloalkyl, substituted C 3-20 -cycloalkyl, unsubstituted C 1-20 -alkoxy, substituted C 1-20 -alkoxy, unsubstituted C 5-20 -aryl, substituted C 5-20 -aryl, unsubstituted C 1-20 -heteroalkyl, substituted C 1-20 -heteroalkyl, unsubstituted C 2-20 -heterocycloalkyl, substituted C 2-20 -heterocycloalkyl, unsubstituted C 4-20 -heteroaryl or substituted C 4-20 -heteroaryl; \n c is 0, 1, 2, 3 or 4; \n d is 0, 1, 2 or 3; \n e is 0, 1, 2, 3, 4 or 5; \n f is 0, 1 or 2; \n g is 0, 1 or 2; \n h is 0, 1, 2, 3 or 4.
