Abstract (en)
[origin: US4575467A] Complex compounds of elements of sub-groups 1 and 8 of the periodic table in oxidation stages 1-4 with unsaturated ketones of the formula <IMAGE> (I) wherein R1 and R4 denote alkyl, cycloalkyl or aryl and R2 and R3 denote hydrogen or alkyl, are outstandingly suitable for activating substrate surfaces for electroless metallization since these complexes are distinguished by a high storage stability. The palladium complexes of but-3-en-2-one and hept-3-en-2-one are preferred.
