1-(Trimethylsiloxy)cyclopentene Chemical Properties,Usage,Production

Chemical Properties

Clear light yellow liquid

Uses

1-(Trimethylsiloxy)cyclopentene may be used in chemical synthesis studies.

Purification Methods

If too impure as seen by the NMR spectrum, then dissolve it in 10 volumes of pentane, shake with cold NaHCO3 (3 x 500mL), then 1.5M HCl (200mL) and aqueous NaHCO3 (200mL) again, dry (Na2SO4), filter, evaporate and distil it through a short Vigreux column (p 11). 1H NMR: (CDCl3) : 0.21 (s, 9H), 1.55 (m, 2H), 1.69 (m, 2H), 2.05 (br d, 4H) and 4.88 (br s, 1H). GLPC in a 6ft x 1/8inch with 3% SP2100 on 100-120 mesh Supelcoport column should give one peak. Store dry. [For the cyclohexene analogue see Varghese et al. Org Synth Coll Vol VIII 460 1993.]
