A PUCKERED TITANACYCLOBUTANE FRAGMENT AS THE RESULT OF A C-C COUPLINGBETWEEN A FULVENE AND A 2-METHYLALLYL LIGAND - STRUCTURE OF (ETA(5)-C(5)ME(5)) [ETA(5)ETA(2)-C(5)ME(4)CH(2)CME(CH2)(2)]TI
Php. Brinkmann et al., A PUCKERED TITANACYCLOBUTANE FRAGMENT AS THE RESULT OF A C-C COUPLINGBETWEEN A FULVENE AND A 2-METHYLALLYL LIGAND - STRUCTURE OF (ETA(5)-C(5)ME(5)) [ETA(5)ETA(2)-C(5)ME(4)CH(2)CME(CH2)(2)]TI, Organometallics, 14(12), 1995, pp. 5481-5482
Reaction of (C(5)Me(5))(C(5)Me(4)CH(2))TiCl and (2 -methylallyl)MgBr l
eads to (eta(5)-C(5)Me(5))[eta(5):eta(2)-C(5)Me(4)CH(2) CMe(CH2)(2)]Ti
(2), a bent metallocene complex wherein a four-membered metallacycle
is tethered to a tetramethyl Cp ligand by a methylene bridge. Thermoly
sis of 2 gives a new fulvene compound: )CH(2))(eta(5):eta(1)-C(5)Me(4)
CH(2)CMe(2)CH(2))Ti (4).
