Abstract
A process to produce an ethylene-bridged-metallocene-transition-metal compound that has an omega-alkenyl substitution on said ethylene bridge is provided. Said process comprises: contacting a diolefin compound with a peracid compound to form an omega-alkenyl oxirane compound; contacting said omega-alkenyl oxirane compound with an organometal compound to form an organo-omega-alkenyl-alcohol compound; contacting said organo-omega-alkenyl-alcohol compound with an organosulfur compound to form an organo-omega-alkenyl-organosulfur ester compound; contacting said organo-omega-alkenyl-organosulfur ester compound with an organometal to form an orgaomega-alkenyl-organo compound; contacting said organo-omega-alkenyl-organo compound with a transition metal compound to form a organo-omega-alkenyl-organo-transition compound. Additionally, processes to polymerize olefins using these compounds is provided.
