Abstract

The present invention relates to a process for preparing a catalyst by activating a catalytic composition which comprisesa) at least one metal of group IB or IIB or a compound thereof,b) where appropriate a carrierwhich comprises treating the composition with an alkyne of the general formula IR1—C≡C—R2  (I)in whichR1 is alkyl, cycloalkyl, aryl, hydroxyalkyl, haloalkyl, alkoxy or alkoxyalkyl,R2 is a hydrogen atom, alkyl, cycloalkyl or aryl, and a carbonyl compound of the general formula II in whichR3 and R4 are, independently of one another, a hydrogen atom, alkyl, haloalkyl, cycloalkyl or aryl,to catalysts obtainable by this process, and to alkynylations and aminoalkylations employing these catalysts.
