(2,4-Pentadienyl)trimethylsilanedisc 06/13/03 Chemical Properties, Uses, Production
Physical properties
bp 41 °C/36 mmHg or 105 °C/760 mmHg; n20/ D 1.4570.
Uses
5-Trimethylsilyl-1,3-pentadiene is a useful pentadienylation reagent; an allyl silane; a precursor for 1-trimethylsilyldienes and intramolecular Diels–Alder substrates).
Preparation
5-Trimethylsilyl-1,3-pentadiene may be prepared in 85% yield by the reaction of pentadienyllithium with chlorotrimethylsilane in THF at room temperature.1–3 Generally the product is ≈95% (E) isomer as judged by IR (strong band at 1000 cm1) or NMR(trans coupling constant of 15.2 Hz for proton at C-3, 5.92 ppm).
storage
Stable liquid; the toxicological properties of this reagent are unknown. It should be handled in a well ventilated hood.
