dcterms:description
Reactions of double tucked-in permethyltitanocene [Ti{eta3:eta4-C5Me3(CH2)2}(eta5-C5Me5)] (1) with t-butanol or propargyl alcohol in toluene proceeded sluggishly even with excess of the alcohol and at elevated temperature. The alcoholysis of 1 with t-butanol afforded [Ti(eta5-C5Me5)(Ot-Bu)3] (3) as the major product and Ti(OtBu)4 as the minor one. The other product of the alcoholysis was pentamethylcyclopentadiene. The only isolated crystalline product was the very minor hydrolytic byproduct [{TiIII(eta5-C5Me5)2}(mu-O){TiIV(Ot-Bu)3}] (2). The alcoholysis of 1 containing traces of LiI with HOCH2C=CH, containing apparently more water than t-BuOH, gave an inseparable mixture of oily products from which several crystals of an unintended hydrolytic byproduct [{Ti(eta5-C5Me5)(OCH2C=CH)(mu-O)}3LiI] (4) were isolated. X-ray crystal structures of 2 and 4 were determined.
