1-Methyl-1,3-cyclopentadiene → HCID 178484295, compound

Participants

Reaction Steps

A 250 mL Schlenk flask is charged with titanium tetrakis(dimethylamide), 3.73 g (16.64 mmole), and toluene, 100 mL. Methylcyclopentadiene, 5.33 g (66.54 mmole), is added to the magnetically stirred solution. The mixture is refluxed 1.5 hours. Solvent and volatiles are removed under vacuum leaving a brown residue. The residue is transferred to a microdistillation apparatus and a forerun of titanium tetrakis(dimethylamide) is distilled from the mixture (at 35°-40° C. and 0.025 mm Hg) followed by a red low melting solid (at 104°-108° C. and 0.025 mm Hg) which is determined to be methylcyclopentadienyltitanium tris(dimethylamide) by proton NMR.
