Abstract
A process is provided comprising contacting a hydrocarbyl lithium with an alkali metal hydrocarbyloxide in the presence of propylene. Optionally, a catalytic support is used during said contacting. Optionally, at least one other alpha-olefin is present during said contacting. In another embodiment a process is provided comprising: (a) contacting a hydrocarbyl lithium with an alkali metal hydrocarbyloxide in the presence of propylene; and thereafter (b) recovering an allyl alkali metal compound; and thereafter (c) contacting said allyl alkali metal compound with at least one alpha-olefin. Optionally, a catalytic support is also used during steps a, b, and c.
