| dc.description.abstractEn | series of pentamethylcyclopentadienyl bis(phosphinimino)methanide complexes of yttrium and the lanthanides, [{CH(PPh2NSiMe3)2}Ln(h5-C5Me5)Cl] (Ln = Y (1a), Sm (1b), Yb (1c)), were prepd. by two different synthetic approaches. The compds. can be obtained either from [{CH(PPh2NSiMe3)2}LnCl2]2 (Ln = Y, Sm, Yb) and K(C5Me5) or in a one-pot reaction when K{CH(PPh2NSiMe3)2} is reacted with anhyd. rare earth trichlorides in the presence of K(C5Me5). When 1a-c were combined in situ with 1 equiv. of 2-propanol, an active [Ln]-OiPr initiator was formed that enabled the pseudo-living ring-opening polymn. of e-caprolactone to polymers with controlled mol. features (end groups, .hivin.Mn) and very narrow molar mass distributions. | |
