Abstract

Настоящее изобретение относится к способу получения α-олефинов олигомеризацией C-C-олефинов. Способ осуществляют олигомеризацией C-C-олефинов в присутствии каталитической системы, содержащей источник переходного металла, активатор, представляющий собой алкилалюмоксан, и соединение формулы (I)где Arявляются одинаковыми или различными и выбраны из замещенных или незамещенных C-C-арилов, R выбран из линейных или разветвленных C-C-алкилов, замещенных или незамещенных C-C-арилов, замещенных или незамещенных C-C-циклоалкилов, причем олигомеризацию проводят в растворителе, представляющем собой бициклическое соединение или смесь бициклических соединений, предпочтительно декалин. Настоящий способ позволяет значительно увеличить активность катализатора при проведении процесса олигомеризации и, как следствие, позволяет снизить расходные нормы катализатора, а также снизить образование побочного полимерного продукта.
