The present invention relates to 3,4-diaminopyridine derivatives of formula (I)
wherein
R1 and R2 are, independently of each other, electron donors, wherein R2 is optionally H; and
R3, R4, R5, and R6 are, independently of each other, H, optionally substituted straight-chain or branched alkyl, alkenyl, alkynyl, alkoxyl, or aryl, wherein R3 and/or R4 together with R5 and/or R6, optionally define a ring;
processes for their preparation, and their use as catalysts.
