<p>2,2-Dimethylcyclopropane-1-carbonyl chloride is a diastereomeric mixture of two diastereoisomers. It is soluble in chloroform and diethyl ether and crystallizes from acetone. 2,2-Dimethylcyclopropane-1-carbonyl chloride is used as a feedstock to produce cyhalothrin, an insecticide that acts by contact. The insecticide is made by esterification of the 2,2-dimethylcyclopropane-1-carbonyl chloride with 3-phenoxybenzaldehyde and then chlorination of the ester.<br>A mixture of two diastereoisomers can be separated using chromatography techniques such as gas chromatography or high performance liquid chromatography (HPLC). In this case it would be possible to use HPLC to separate the two diastereoisomers.</p>

<p>4-(Cyanomethyl)benzoic acid is a photocurrent generating molecule that has been shown to be an efficient acceptor in organic photovoltaic devices. It is also used as a sensitizer for the production of benzothiadiazole. The functional theory behind this reaction is that 4-(Cyanomethyl)benzoic acid first acts as an electron acceptor and then becomes a proton donor by accepting hydrogen from benzonitrile, which leads to the formation of benzothiadiazole. The bathochromic shift of the absorption spectrum of 4-(Cyanomethyl)benzoic acid was observed due to the presence of benzothiadiazole. This molecule can be used for solar cells because it contains a dipole, which facilitates charge separation and recombination in solar cells.</p>
