Dichloromethane is widely used as a solvent in part because it is relatively inert. It does participate in reactions with certain strong nucleophiles however. Tert-butyllithium deprotonates DCM: [20] H 2 CCl 2 + RLi → HCCl 2 Li + RH. Methyllithium reacts with methylene chloride to give chlorocarbene: [citation needed]
This chemical reaction is typical of alkanes and alkyl-substituted aromatics under application of UV light. The reaction is used for the industrial synthesis of chloroform (CHCl 3), dichloromethane (CH 2 Cl 2), and hexachlorobutadiene. It proceeds by a free-radical chain mechanism.
Deuterated dichloromethane (CD 2 Cl 2 or C 2 H 2 Cl 2) [a] is a form (isotopologue) of dichloromethane (DCM, CH 2 Cl 2) in which the hydrogen atoms (H) are deuterium (heavy hydrogen) (2 H or D). [2] Deuterated DCM is not a common solvent used in NMR spectroscopy as it is expensive compared to deuterated chloroform .
The reaction uses a hypervalent iodine reagent [2] similar to 2-iodoxybenzoic acid to selectively and mildly oxidize alcohols to aldehydes or ketones. The reaction is commonly conducted in chlorinated solvents such as dichloromethane or chloroform. [2] The reaction can be done at room temperature and is quickly complete.
The handling of this chemical may incur notable safety precautions. ... Structure and properties ... log 10 of Dichloromethane vapor pressure.
Dichlorocarbene is an intermediate in the carbylamine reaction. In this conversion, a dichloromethane solution of a primary amine is treated with chloroform and aqueous sodium hydroxide in the presence of catalytic amount of the phase-transfer catalyst. Illustrative is the synthesis of tert-butyl isocyanide: [7]
1,2-Dichloroethylene or 1,2-DCE is the name for a pair of organochlorine compounds with the molecular formula C 2 H 2 Cl 2.The two compounds are isomers, each being colorless liquids with a sweet odor.
1,1-Dichloroethylene, commonly called vinylidene chloride or 1,1-DCE, is an organochloride with the molecular formula CCl 2 CH 2.It is a colorless liquid with a sharp odor. Like most chlorocarbons, it is poorly soluble in water but soluble in organic solvents. 1,1-DCE was the precursor to the original clingwrap, Saran, for food, but this application has been phased
