1. A compound of formula (I)wherein
R1 is H, C3-C8cycloalkyl, which is optionally substituted by C1-C8alkyl, or C1-C8perfluoroalkyl; or C1-C8alkyl, and R2 is H, or C1-C8alkyl, or R1 is a group of formula and R2 is H; R4 is C1-C8alkyl, CF3, or NR7R9, R4′ is H, CF3 or C1-C8alkyl R4″ is C1-C8alkyl, or CF3, R7 and R9 are independently of each otheror
R7 and R9 together with the nitrogen atom to which they are bonded form a group of formula R10 is H, or C1-C8alkyl, or R1 and R2 together form a ring —(CH2)3—, or —(CH2)4—, which are optionally substituted by one or two C1-C8alkyl and/or by one or two C1-C8perfluoroalkyl, R3 and R8 are independently of each other C1-C8alkyl, —Si(C1-C8alkyl)3, or C3-C8cycloalkyl; M is Pt, Pd, Rh, Ir, or Re, L is a mono-, or bi-dentate ligand, if L is a monodentate ligand,
m is 0, or 2, and n is 1, or 2, if M is Pd, or Pt,m is 0, 2, or 4, and n is 1, 2, or 3, if M is Rh, Ir or Re, if L is a bidentate ligand,
