(Triisopropylsilyl)acetylene Chemical Properties,Usage,Production
Chemical Properties
clear colorless liquid
Physical properties
colorless clear liquid; bp 50–52 °C at 0.8 hPa (0.6 mmHg), flash point 56 °C (closed cup); d = 0.813.
Uses
(Triisopropylsilyl)acetylene may be used as reagent for the rhodium-catalyzed asymmetric alkynylation of various α,β-unsaturated ketones. It may be used as reagent in the enantioselective synthesis of β-alkynylated nitroalkanes.
Uses
(Triisopropylsilyl)acetylene (TIPS-acetylene) is an easily handled and inexpensive monoprotected acetylene used as an attractive substitute for trimethylsilylacetylene (TMSacetylene). The bulkier silyl protecting group of TIPS-acetylene provides stability in a wider range of reaction conditions than TMS-acetylene. Its higher boiling point also provides better handling and safety than TMS-acetylene (bp 87–88°C at 12 hPa (9 mmHg)). The general utility of TIPS-acetylene is often highlighted in the transition metal-catalyzed C–C bond formations， including but not limited to transition metal-catalyzed Coupling Reactions；Reaction of TIPS-acetylide with Electrophiles；Synthesis of Polyynes；Transition Metal-catalyzed Cross-addition of TIPSacetylene to Alkynes；Hydroalkynylation；Direct Alkynylation；Conjugate Addition；Cycloaddition；Ring-opening Reactions etc.
General Description
Asymmetric addition of (triisopropylsilyl)acetylene to α,β,γ,δ-unsaturated carbonyl compounds in the presence of a cobalt/Duphos catalyst is reported. A Sonogashira coupling reaction between 1-bromo-3-iodo-5-tertbutylbenzene and (triisopropylsilyl)acetylene is reported.
storage
(Triisopropylsilyl)acetylene (Ethynyltriisopropylsilane) is stable to air and moisture, incompatible with strong acids, bases, or oxidants, and flammable vapor and liquid. Skin/eye contact and inhalation should be avoided.
