The present invention relates to a process for preparing a catalyst by activating a catalytic composition which comprises
a) at least one metal of group IB or IIB or a compound thereof,
b) where appropriate a carrier
which comprises treating the composition with an alkyne of the general formula I
R1—C≡C—R2 (I)
in which
R1 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 which
R3 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.
本发明涉及一种制备催化剂的工艺,该工艺通过激活催化组分来制备催化剂,该催化组分包括a)至少一种IB或IIB族金属或其化合物,b)适当时还包括载体,该载体通过用一般式IR1—C≡C—R2的炔处理组分来制备,式中R1是烷基、环烷基、芳基、羟基烷基、卤代烷基、烷氧基或烷氧基烷基,R2是氢原子、烷基、环烷基或芳基,以及一般式II的羰基化合物,其中R3和R4分别是氢原子、烷基、卤代烷基、环烷基或芳基,所得到的催化剂以及使用这些催化剂进行炔基化和氨基烷基化。
