A functional chain transfer agent , bis(10‐undecenyl)magnesium, was employed as cocatalyst in conjunction with [(C 5 Me 5 ) 2 NdCl 2 Li(OEt 2 ) 2 ] to catalyze polyethylene (PE) chain growth on magnesium. Vinyl‐PE‐Mg‐PE‐vinyl units were then further functionalized. This is the first example of catalytic ethylene polymerization with single‐step, in situ functionalization to telechelic polyethylenes.
