Ethene Elimination during Thermolysis of Bis(3-butenyltetramethylcyclopentadienyl)dimethyltitanium
Original language description
Thermolysis of [TiMe(2){eta(5)-C(5)Me(4)(CH(2)CH(2)CH=CH(2))}(2)] (1) in toluene at 120 C for 4 h resulted in the formation of the cyclopentadiene ring-tethered titanacyclobutane [Ti(IV){eta(5)-C(5)Me(4)CH(2)CH(2)CH(kappa-CH)}(2)CH(2)] (2) in virtually quantitative yields. Thermolysis in an NMR tube at 100 C revealed that initial elimination of methane is followed by addition of one 3-butenyl double bond to a titanocene methylidene moiety. The formed titanacyclobutane intermediate [Ti{eta(5)-C(5)Me(4)(CH(2)CH(2)CH=CH(2))} {eta(5)-C(5)Me(4)CH(2)CH(2)CH (kappa-CH)CH(2)CH(2)-(kappa-CH(2))}] (4) then underwent a metathesis reaction with the pendant 3-butenyl to give 2 and free ethene. Cleavage of Ti-C bonds of 2 with HCl afforded stable ansa-[TiCl(2){eta(5)-C(5)Me(4)(CH(2))(7)eta(5))-C(5)Me(4)}] (3). Sunlight photolysis of 1 gave rise to the cyclopentadiene ring-tethered titanacyclopentane [Ti(IV){eta(5)-C(5)Me(4)(CH(2)CH(2)CH(kappa-CH)CH(2)}(2)] (5), the known product of cycloaddition rea
