4-Isopropylcyclohexylmethanol is a synthetic chemical that is used as a fragrance. It is found in plants such as Paeonia suffruticosa and is used in the synthesis of linalool oxide. 4-Isopropylcyclohexylmethanol has been shown to bind to histone proteins, which may have an effect on gene expression. This chemical also has a vapor pressure of 0.0013 mmHg at 25°C and can be detected by electrochemical method at a concentration of 10 ppm. 4-Isopropylcyclohexylmethanol has been shown to react with eugenol in benzene, forming methyl cinnamate and methyl ethyl alkanal.

tert-Butyl 6-aminohexanoate is a benzene derivative that is used as a spacer in organic synthesis. It reacts with potassium carbonate to form tert-butyl 6-aminocaproate and tert-butyl 2,6-dinitrophenolate. The tert-butyl group has an amino group at one end and a carboxylic acid group at the other end. This tertiary amine is made by reacting benzene with potassium hydroxide and adding 1-4c alkyl chloride. The tertiary amine functional group is reactive towards electrophilic aromatic substitution reactions, such as nitration or halogenation.

1-(Ethenesulfonyl)-4-nitrobenzene (1ESNB) is a pyrazoline that has been used as an oxidant in cyclic aliphatic and heterocyclic syntheses. 1ESNB is also used to form phosphate derivatives, which are important in the pharmaceutical industry. 1ESNB can be prepared by the organocatalytic coupling of ethyl sulfone with nitrobenzene. The azomethine ylide can be generated from 1ESNB through oxidation with potassium permanganate or ozone, followed by addition of an aliphatic amine. This reaction gives a quinolinium salt that can be converted to a sulfone using thionyl chloride or oxalyl chloride. A cycloaddition reaction can then convert the sulfone into a biologically active molecule such as methotrexate or daunorubicin.
