Short chain length α-olefins have found numerous applications for the preparation of commercially relevant compounds. 1 Particularly, they are used as comonomers in the synthesis of low-density polyethylene. Among processes that are able to furnish α-olefins (cracking of paraffins, dehydrogenation, dehydration, chain growth) the oligomerisation of ethylene is probably the most rewarding process since it can produce selectively C 4 , C 6 and C 8 α-olefins which ...
