Abstract:
A complex of the formula I, wherein Nu is selected from the group consisting of O, S, Nâ€”R4*, and P-R4*; M is Ni or Pd; h is an integer from 0 to 4; X are the same or different and are selected from the group consisting of a halogen, C1-C8-alkyl, C3-C12-cycloalkyl, C7-C13-aralkyl and C6-C14-aryl, R1, R4, R4* are the same or different and are selected from the group consisting of hydrogen, substituted or unsubstituted C1-C18-alkyl, substituted or unsubstituted C2-C18-alkenyl comprising from one to 4 isolated or conjugated double bonds and is bound via a single bond, substituted or unsubstituted C3-C12-cycloalkyl, C7-C3-aralkyl, unsubstituted or substituted C6-C14-aryl, and unsubstituted or substituted five- to six-membered nitrogen-containing heteroaryl radicals which are bound via a single bond; R2 is an unsubstituted or substituted C6-C14-aryl, or an unsubstituted or substituted five- to six-membered nitrogen-containing heteroaryl radical; R3, R8 are each selected from the group consisting of C1-C18-alkyl, substituted or unsubstituted C2-C18-alkenyl comprising from one to 4 isolated or conjugated double bonds, substituted or unsubstituted C3-C12-cycloalkyl, C7-C13-aralkyl, unsubstituted or substituted C6-C14-aryl, or a unsubstituted or substituted five- to six-membered nitrogen-containing heteroaryl radical; wherein adjacent radicals R1 to R4 or R4* may be joined to one another to form a 5- to 12-membered ring which may comprise a substituent selected from the group consisting of substituted or unsubstituted C1-C8-alkyl, substituted or unsubstituted C2-C8-alkenyl comprising from one to 4 isolated or conjugated double bonds, substituted or unsubstituted C3-C12-cycloalkyl, C7-C13-aralkyl, and C6-C14-aryl; L1 is an uncharged, organic or inorganic ligand.
