DIPEA is a sterically hindered organic base that is commonly employed as a proton scavenger. Thus, like 2,2,6,6-tetramethylpiperidine and triethylamine, DIPEA is a good base but a poor nucleophile, DIPEA has low solubility in water, which makes it very easily recovered in commercial processes, a combination of properties that makes it a useful organic reagent.
Diisopropylamine is a common amine nucleophile in organic synthesis. [4] Because it is bulky, it is a more selective nucleophile than other similar amines, such as dimethylamine.
Isopropylamine can be obtained by reaction of isopropyl alcohol with ammonia in presence of a catalyst: [3] (CH 3) 2 CHOH + NH 3 → (CH 3) 2 CHNH 2 + H 2 O. Isopropylamine is a building block for the preparation of many herbicides and pesticides including atrazine, bentazon, glyphosate, imazapyr, ametryne, desmetryn, prometryn, pramitol, dipropetryn, propazine, fenamiphos, and iprodione.

From left to right: the two isomeric groups propyl and 1-methylethyl (iPr or isopropyl), and the non-isomeric cyclopropyl group. In organic chemistry, a propyl group is a three-carbon alkyl substituent with chemical formula −CH 2 CH 2 CH 3 for the linear form.
Short-chain alkyl halides are often carcinogenic.. The bromine atom is at the secondary position, which allows the molecule to undergo dehydrohalogenation easily to give propene, which escapes as a gas and can rupture closed reaction vessels.
Ethylamine, also known as ethanamine, is an organic compound with the formula CH 3 CH 2 NH 2.This colourless gas has a strong ammonia-like odor.It condenses just below room temperature to a liquid miscible with virtually all solvents.
Structure [ edit ] In the early 1990s, theoretical studies and electron diffraction analysis of the 3D structure of the molecule, in the gas phase or in non-polar solvents, indicated that the bonds between the nitrogen atom and the three carbon atoms were nearly coplanar in the ground state, instead of forming a trigonal pyramid as in simpler ...
