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.
Claims32
A process to produce an allyl alkali metal alkene addition catalyst and a single alkene addition product said process consisting essentially of contacting:
- a hydrocarbyl lithium;
- with
- an alkali metal hydrocarbyloxide wherein said alkali metal is selected form the group consisting of sodium, potassium, cesium, rubidium, and mixtures thereof;
- in the presence of propylene;
- and
- recovering said allyl alkali metal alkene addition catalyst and said single alkene addition product.
A process to produce a single alkene addition product said process consisting essentially of contacting:
- a hydrocarbyl lithium;
- with
- an alkali metal hydrocarbyloxide wherein said alkali metal is selected from the group consisting of sodium, potassium, cesium, rubidium, and mixtures thereof;
- in the presence of a molar excess of propylene;
- and
- recovering said single alkene addition product.
A process to produce 4-methyl-1-pentene said process consisting essentially of contacting n-butyl lithium and potassium tert-butoxide to form a first mixture followed by contacting said first mixture with a molar excess of propylene and then recovering said 4-methyl-1pentene.
A process to produce an allyl alkali metal alkene addition catalyst said process consisting essentially of contacting:
- a hydrocarbyl lithium;
- with
- an alkali metal hydrocarbyloxide wherein said alkali metal is selected from the group consisting of sodium potassium, cesium, rubidium, and mixtures thereof;
- in the absence of a molar excess of propylene;
- and
- recovering said allyl alkali metal alkene addition catalyst.
A process to produce an allyl potassium alkene addition catalyst said process consisting essentially of contacting n-butyl lithium and potassium tert-butoxide to form a first mixture followed by contacting said first mixture with propylene and then recovering said allyl potassium alkene addition catalyst.
