What is the pKa of diisopropylamine?
Diisopropylamine has a pKa value of 36.
Is diisopropylamine soluble in water?
Diisopropylamine has a density of 0.722 at 220.0”C and is soluble in water and alcohol (Windholz et al., 1983; Sax, 1979).
Is diisopropylamine safe?
* Breathing Diisopropylamine can irritate the lungs causing coughing and/or shortness of breath. Higher exposures can cause a build-up of fluid in the lungs (pulmonary edema), a medical emergency, with severe shortness of breath. * High exposure can cause headache, nausea and vomiting.
What is diisopropylamine used for?
The main commercial applications of diisopropylamine is as a precursor to two herbicides, diallate and triallate, as well as certain sulfenamides used in the vulcanization of rubber. It is also used to prepare N,N-Diisopropylethylamine (Hünig’s base) by alkylation with diethyl sulfate.
How do you generate LDA?
- Dilute with ether and cool to 0oC.
- Slowly add 0.04x mL water.
- Add 0.04x mL 15 % aqueous sodium hydroxide.
- Add 0.1x mL water.
- Warm to RT and stir 15 min.
- Add some anhydrous magnesium sulfate.
- Stir 15 min and filter to remove salts.
How do you purify diisopropylamine?
Diisopropylamine is purified by heating to reflux over sodium hydroxide (NaOH) for 3–12 hr, followed by simple distillation from NaOH. 4. Butyllithium in hexanes (2.5 M) is purchased from Aldrich Chemical Company, Inc., and titrated using diphenylacetic acid.
How do you make LDA solution?
What is the full form of LDA?

How do you quench an LDA reaction?
Quenching Reactions: Lithium Aluminium Hydride
- Dropwise addition of a saturated aqueous sodium sulfate (Na2SO4).
- For each (one) gram of lithium alumninium hydride used, add dropwise one ml water followed by one ml of 15% aqeuous NaOH and, finally, 3 ml of water.
Is LDA a reducing agent?
Lithium Diisopropylamide (LDA) as an Efficient Reducing Agent for Thioketones—Mechanistic Consideration. Treatment of thiocarbonyl compounds with excess of lithium diisopropylamide (LDA) leads to corresponding thiols or sulfides depending on the work-up procedure.
Is LDA a weak nucleophile?
Strong organic bases such as LDA (Lithium DiisopropylAmide) can be used to drive the ketone-enolate equilibrium completely to the enolate side. LDA is a strong base that is useful for this purpose. The steric bulk of its isopropyl groups makes LDA non- nucleophilic. Even so, it’s a strong base.
What is the molecular formula of diisopropylamine?
Diisopropylamine Common Name Diisopropylamine Diisopropylamine Diisopropylamine CAS Number 108-18-9 Molecular Weight 101.19000 Density 0.722 g/mL at 25 °C (lit.) Boiling Point 84 °C (lit.) Molecular Formula C 6 H 15 N Melting Point -61 °C MSDS Chinese USA Flash Point 1.4 °F
How is diisopropylamine degraded in the atmosphere?
Vapor-phase diisopropylamine will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 4 hours. If released to soil, diisopropylamine is expected to have high mobility based upon an estimated Koc of 140.
Which is more selective LDA or diisopropylamine?
Diisopropylamine is a colorless liquid with an ammonia-like odor. Its lithium derivative, lithium diisopropylamide, known as LDA is a widely used reagent. Diisopropylamine is a common amine nucleophile in organic synthesis. Because it is bulky, it is a more selective nucleophile than, say, dimethylamine.
How big is the flash point of diisopropylamine?
More details: Density: 0.7±0.1 g/cm 3 Boiling Point: 83.9±0.0 °C at 760 mmHg Vapour Pressure: 74.0±0.1 mmHg at 25°C Enthalpy of Vaporization: 30.4±0.0 kJ/mol Flash Point: -6.1±0.0 °C
