Effect of ketene additive and Si/Al ratio on the reaction of methanol over HZSM-5 catalysts

The influence of ketene as possible intermediate for the reaction of methanol to aromatics was investigated over HZSM-5 catalysts (Si/Al ratio of 15 and 9) using diketene-acetone (2,2,6-trimethyl-4H-1,3-dioxin-4-one) as ketene precursor under atmospheric

(Cycloalkylmethyl)bis(η5-cyclopentadienyl)titanium(III) Complexes

Reaction of bis(cyclopentadienyl)titanium dichloride (1) and isopropylmagnesium bromide (2) with the methylenecycloalkanes 3-8 (cyclopropane), 35 (cyclobutane), and 37 (cyclopentane) leads to the (cycloalkylmethyl)bis(cyclopentadienyl)titanium(III) compounds 9-14, 36, and 38.The cyclopropylmethyl complexes 12-14, which have et least two geminal methyl substituents, are stable.Compounds 9-11, 36, and 38, in which appropriate substituents are lacking, rearrange by ring opening followed by C=C bond isomerization to give the (η3-allyl)bis(η5-cyclopentadienyl)titanium complexes 23-26 and 40.
