摘要:
1-Butenes are selectively produced via the dimerization of 1-olefins in the presence of novel organotantalum catalysts comprising tantalum and a silyl-substituted cyclopentadienyl moiety having the formula C.sub.5 H.sub.5-x (SiR.sup.6.sub.3).sub.x, wherein each R.sup.6 may be the same or different and is hydrogen, alkyl, cycloalkyl, aryl, aralkyl or alkoxy, and x is an integer from 1 to 5.
