Procedure

To a solution of 3.69 g (50.4 mmol) tert-butyl amine in 45 mL THF was added 2.00 g (12.6 mmol) (chloro)(cyclopentadienyl)(dimethyl)silane. Precipitate formed quickly. The slurry was stirred for several days, then the amine hydrochloride was filtered off and the solvent was removed under reduced pressure to give the product as a very pale yellowish oil. The yield was 2.069 g (84.2%). Mass spec: m/e 195 (6%). 1H and 13C NMR show the presence of several cyclopentadiene isomers.
