COORDINATION COMPLEX SYSTEM COMPRISING TAUTOMERIC LIGANDS

摘要

The invention relates to a coordination complex system comprising a ligand (1) having the formula: R 1 -SO 2 -NH-P(XR 2 ) 2 (1a) ; or R 1 -SO 2 -N=PH(XR 2 ) 2 (1b); or R 1- SO(OH)=N-P(XR 2 ) 2 (1c) ; wherein X is independently O, S, NH, or a bond; R 1 and R 2 are independently selected from substituted or unsubstituted alkyl and aryl; wherein at least one equivalent of a ligand (1) is complexed to a metal selected from a transition metal and lanthanide; wherein Y is O, S, NH, or a bond.
The invention also relates to the use of said coordination complexes as catalysts in the hydroformylation, hydrogenation, transfer hydrogenation, hydrocyanation, polymerization, isomerization, carbonylation, cross-coupling, metathesis, CH activation, allylic substitution, aldol condensation, or Michael addition.
