A SN1 Reaction: Synthesis of tert-Butyl Chloride Supplementary Material Experiment Notes: This lab experiment proposes the synthesis of an alkyl halide by reacting the corresponding alcohol with a hydrogen halide in an easy and inexpensive SN1 reaction. 1,2 tert-Butanol reacts readily with HCl and forms the corresponding tert-butyl chloride at About 80% of commercially produced ammonia is used in agricultural fertilizers. Ammonia is also used as a corrosion inhibitor, in water purification, as a household cleaner, as an antimicrobial agent in food products, as a refrigerant, as a stabilizer in the rubber industry, as a source of hydrogen in the hydrogenation of fats and oils, and as a chemical intermediate in the production of

Tert-Butyl nitrite (TBN) is a multitask reagent for the controlled synthesis of N-nitrosoamides from N-alkyl amides, hydrolysis of N-methoxyamides to carboxylic acids, metal-free benzocoumarin synthesis from ortho-aryl-N-methoxyamides, and Ru-catalyzed isocoumarin synthesis. Tert-Butyl nitrite is employed as a reagent for diazotization and nitrosation of alcohols, thiols, amines and cycloalkanes. It plays an important role in photocatalyzed conversion of aryl and heteroarylamines to selenides. It finds application in the preparation of aryl azides from aryl amines. A conversion of o-phenylenediamines into benzotriazoles was achieved at room temperature using tert-butyl nitrite. The optimized conditions are also well suited for the transformation of sulfonyl and acyl hydrazines into corresponding azides. This protocol does not require any catalyst or acidic medium.
