General Description

2-Chlorobut-2-enoic acid, also known as 2-Chloroacrylic acid, is a chemical compound with the molecular formula C4H5ClO2. It is a colorless liquid with a pungent odor, and is classified as a chloroacrylate. 2-Chlorobut-2-enoic acid is mainly used as an intermediate in the production of pharmaceuticals and agrochemicals, as well as in the synthesis of other organic compounds. It is also used as a building block in the production of polymers and resins. However, 2-Chlorobut-2-enoic acid is considered to be a hazardous substance, and exposure to it can cause irritation to the skin, eyes, and respiratory system. Additionally, it has the potential to cause environmental harm if not handled and disposed of properly.

The reactions of ethyl-, vinyl-, and ethynyl(trichloromethyl)carbinols with aqueous amd methanolic potassium hydroxide, thiourea, and cyanamide

The reactions of ethyl(trichloromethyl)carbinol, dimethyl(trichloromethyl)carbinol. (trichloromethyl)vinylcarbinol, ethynyl(trichloromethyl)carbinol, and 1,1,1-trichloro-3-nonyn-2-ol have been studied with the following reagents.Methanolic potassium hydroxide: α-methoxy acids are formed in 70 and 79 percent yields with the ethyl- and vinylcarbinols respectively.Double bond migration to the conjugated position was observed with the vinylcarbinol.Thiourea: substituted 2-imino-4-thiazolidinones are formed in 27 to 66 percent yield with the first three carbinols with double bond migration in the case of the vinylcarbinol.Cyanamide: the saturated carbinols were converted to substituted ethyl 2-imino-4-oxo-1-imidazolidinecarboximidates in 30 to 60 percent yield.Aqueous potassium hydroxide: α-chloro acids were formed from the ethyl- and vinylcarbinols in 23 and 24 percent yields respectively, again with double bond migration in the case of the vinylcarbinol.The results are discussed in terms of the known parallel reactions with phenyl(trichloromethyl)carbinol, and provide information which illustrates the usefulness and defines the limits of certain known synthetic reactions when applied to the alkyl, alkenyl, and alkynyl trichloromethylcarbinols.
