Reactivity of [{Y(C5Me5)(OC6H3But2)(µ-H)}2] with terminal alkene and alkynes: a model for the first insertion step in alkene polymerization
Abstract
Terminal alkenes H2CCHR (R = H, Me, Bun) react with [{Y(C5Me5)(OAr)(µ-H)}2]1 to give the µ-n-alkyl species trans-[{Y(C5Me5)(OAr)}2(µ-H)(µ-CH2 CH2R)](R = H 2, Me 3, Bun4), respectively; HC
CSiMe3 reacts to give [{Y(C5Me5)(OAr)}2(µ-H)(µ-C
CSiMe3)]5.
