2-amino or 2-hydroxy-2-phosphinoalkanoate nickel derivatives, obtainable by the reaction of 2-amino- or 2-hydroxy-2-phosphinoalkanoic acid derivatives or 2-phosphoniobis (2-hydroxyalkanoic acid) derivatives of the general formula II, wherein A equals - + NHR 4 R 5 (Type 1) or -OH (with + NH 2 R 4 R 5 as counterion: type 2), X from the group -C ((COO - ) (OH) R 1 ) (type 3, when A = -OH and with + NH 2 R 4 R 5 as counterion), free electron pair (no substituent) and boron compound BR 3 (BH 3 , B (alkyl) 3 , B (aryl) 3 or B (perfluoroaryl) 3 ) is selected, R 1 is a hydrogen atom or a C l -C 12 alkyl radical or a C 6 -C 19 -aryl radical, R 2 , R 3 , R 4 and R 5 are independently hydrogen, C 1 -C 12 -n-alkyl groups, C 1 -C 12 branched alkyl groups, C 1 -C 12 cycloalkyl groups, C 1 -C 12 alkoxy groups, C 1 -C 12 alkenyl groups, C 7 -C 20 arylalkyl groups, C 6 -C 19 -aryl groups, C 6 -C 14 aryl groups which are the same or different substituted by one or more C 1 -C 12 alkyl groups, C 1 -C 12 alkoxy groups or halogens, or for OR 6 or NR 6 R 7 stand, where two of the radicals R 2 and R 3 or R 4 and R 5 optionally together contain a saturated or unsaturated ring ... |
