Usage

General Description

α,α-Dichlorophenylacetic acid, also known as Dichlorophenoxyacetic acid or 2,2-dichloro-2-phenylacetic acid, is a synthetic compound that belongs to the class of organic chemicals known as haloacetates. This chemical is commonly used as a herbicide that is effective in killing broadleaf weeds and woody plants. α,α-Dichlorophenylacetic acid works by mimicking the natural plant growth hormone auxin, causing uncontrolled and abnormal growth in the targeted plants leading to their eventual death. However, this chemical has been linked to various environmental and health concerns due to its persistence in the environment and potential toxicity to humans and wildlife. It is important to handle and dispose of α,α-Dichlorophenylacetic acid with caution to minimize its negative impacts on the environment and human health.

Halogen atom transfer radical cyclization of N-allyl-N-benzyl-2,2-dihaloamides to 2-pyrrolidinones, promoted by Fe0-FeCl3 or CuCl-TMEDA

The halogen atom transfer radical cyclization of a N-allyl-N-benzyl-2,2-dihaloamides to 2-pyrrolidinones has been carried out in high yields under mild conditions, in a reaction promoted by CuCl-TMEDA or Fe0-FeCl3 in acetonitrile or N,N-dimethylformamide, respectively.

Chlorinations with Carbon Tetrachloride under Conditions of Phase Transfer Catalysis

Anion of ketones, sulfones and esters were α-chlorinated by carbon tetrachloride under conditions of phase transfer catalysis (PTC).Alcohols were unreactive.The observed products show that secondary reactions took place in many cases.The chlorination of the sulfone cis-2,5-diphenyltetrahydrothiophene-1,1-dioxide (1) occurred with inversion to give trans-2,5-dichloro-2,5-diphenyltetrahydrothiophene-1,1-dioxide (2).The structures of cis-1 and trans-2 were determined by X-ray diffraction.The reaction conditions are also applicable to brominations using bromotrichloromethane.
