General description

3,3-Dimethyl-1-butene oxidizes selectively to corresponding epoxide by chlorine promoted Ag(111) oxygen adatoms. 3,3-Dimethyl-1-butene undergoes copolymerization with ethylene using a chain-walking Pd-diimine catalyst. Cationic polymerization of 3,3-dimethyl-1-butene (tert-butyl ethylene) has been carried out using AlCl3catalyst in ethyl chloride solvent in the temperature range -31 to -130°C.
