D. Jeremic et al., POLYMERIZATION OF NORBORNENE AND 1,5-HEXADIENE BY [CP-ASTERISK-TIME(2)][MEB(C6F5)(3)], Journal of organometallic chemistry, 497(1-2), 1995, pp. 143-147
Reaction of CpTiMe(3) with B(C6F5)(3) results in methyl abstraction a
nd formation of the compound [CpTiMe(2)][MeB(C6F5)(3)]. The thus form
ed 10-electron, cationic species [CpTiMe(2)](+) is an excellent initi
ator for polymerization of norbornene via Ziegler and ring opening met
hasis processes and of 1,5-hexadiene via cyclopolymerization and Ziegl
er processes.
