Dichlorocarbene is the reactive intermediate with chemical formula CCl2. Although this material has not been isolated, it is a common intermediate in organic chemistry, being generated from chloroform. This bent diamagnetic molecule rapidly inserts into other bonds.
==Preparation==
Dichlorocarbene is most commonly generated by reaction of chloroform and a base such as potassium ''t''-butoxide or aqueous sodium hydroxide.〔Organic Syntheses, Coll. Vol. 5, p.874 (1973); Vol. 41, p.76 (1961).()〕 A phase transfer catalyst, for instance benzyltriethylammonium bromide, facilitates the migration of the hydroxide in the organic phase.
