Oligomerisation and Stereoselective Polymerisation of Alkenes and Alkynes Using Pyridyl-based Al(III) Catalysts

Dealkylation of the dimers [R2Al(2-py')]2 (2-py’ = 6-substituted pyridyl, R = Me, iBu) with [Ph 3 /sub>C][B(C6 F 5 ) 4 ] gives the putativecations [RAl( 2 -py') 2 (μ-R)AlR] + which can polymerise a range of alkenes with a high degree...
