<p>3-benzyl-3-azabicyclo[3.1.1]heptan-6-one (BAH) is a selective derivatization reagent that reacts with ketones to form cyclobutanes, which are more stable than the corresponding ketones. The product is selectively derivatized at the nitrogen atom of the piperidine ring. BAH is used as a chemical intermediate in medicinal chemistry, such as for the synthesis of piperidines and other heterocycles. This compound has been shown to be efficient in converting 1,2-dihydropyridines into 1,2-dihydroquinolines with high yields and high levels of purity. BAH is also used for the synthesis of multigram quantities of peptides and proteins by postsynthetic modifications on natural amino acids or unnatural amino acids with reactive functional groups such as azide or bromide.</p>

<p>4-Chloro-1H-benzimidazole is a synthetic nucleophile that reacts with thioethers to form an ion pair. It can be used as a precursor for the synthesis of captopril, an antihypertensive drug. 4-Chloro-1H-benzimidazole is also known to react with carboxylic acids to form ion pairs and then dehydrate to form electrostatically bound products. The reaction mechanism starts with the nucleophilic attack of a proton on the carbonyl carbon atom in the carboxylic acid, forming an intermediate carbocation which reacts with a chloride ion. This intermediate then collapses and forms two products: one positively charged and one negatively charged. The positively charged product is a chloroformate salt while the negatively charged product is an alcohol.</p>

<p>2,6-Dimethoxybenzonitrile is an organic compound with the formula C8H9NO2. It is a white solid that is soluble in water and polar organic solvents. 2,6-Dimethoxybenzonitrile has three stereoisomers: Z, E and E. The Z form is usually obtained as a mixture of two diastereomers. The other two forms are obtained by reacting with methylamine or acetonitrile respectively. The photodecomposition of 2,6-dimethoxybenzonitrile starts with the generation of nitric oxide (NO) and then formation of quinones such as 9-acetylphenanthrene, which can react with triazolium to generate pyridinium. The reaction mechanism for this process involves bond cleavage followed by methylation reactions at the benzenes and cyanides.</p>
