Abstract
The invention describes a catalytic composition obtained by interaction of an alkyl titanate on the one hand with a preformed mixture of an alkylaluminium and a Lewis base on the other hand. The invention also describes the use of said composition in a process for the selective dimerization of ethylene to 1-butene.
