Usage

General Description

Benzhydrylidene dibromide, also known as (2,2-dibromovinyl)dibenzene, is a chemical compound with the formula C14H10Br2. As indicated by its systematic name, it is characterized by two bromine atoms attached to a vinyl group, with this group being attached to two benzene rings. It is a member of the bromobenzenes family and appears as an off-white crystalline powder. This chemical compound is mainly used as an intermediate to produce other chemical products, and it can be hazardous to human health if ingested, inhaled, or comes in contact with skin and eyes.

Ferric(III) Chloride Catalyzed Halogenation Reaction of Alcohols and Carboxylic Acids Using α,α-Dichlorodiphenylmethane

A new method for chlorination of alcohols and carboxylic acids, using α,α-dichlorodiphenylmethane as the chlorinating agent and FeCl3 as the catalyst, was developed. The method enables conversions of various alcohols and carboxylic acids to their corresponding alkyl and acyl chlorides in high yields under mild conditions. Particulary interesting is the observation that the respective alkyl bromides and iodides can be generated from alcohols when either LiBr or LiI are present in the reaction mixtures.

ELECTROCHEMICAL CYCLIZATION OF TETRAMETHYL ESTERS OF 2-SUBSTITUTED PROPANE-1,1,3,3-TETRACARBOXYLIC ACIDS IN THE PRESENCE OF SALTS OF HYDROHALIC ACIDS

The chemical and electrochemical cyclization of tetramethyl esters of 2-substituted propane-1,1,3,3-tetracarboxylic acids in the presence of hydrohylic acid salt mediators were studied.It was found that the chemical variant of the cyclization of the corresponding α,α'-dianions of esters of propane-1,1,3,3-tetracarboxylic acids by the action of iodine or bromine is substantially inferior to the electrochemical variant.In the latter case, the esters of substituted cyclopropane-1,1,3,3-tetracarboxylic acids are formed in a 87-98percent yield.The tetramethyl ester of 2-isopropylpropane-1,1,3,3-tetracarboxylic acid, which under the electrolysis conditions decomposes according to a Michael retroreaction is an exception.
