4-Chloro-7-nitrobenzofurazan (NBD-Cl) is a highly sensitive chromogenic and fluorogenic reagent. It is reported to react spontaneously with trans-1-methoxy-3-(trimethylsilyloxy)-1,3-butadiene (Danishefsky′s diene), to afford regioselectively the silyl enol ether, via normal electron-demand Diels-Alder (NEDDA) reaction. A study of the molecular structure, vibrational spectra and NBO (Natural Bond Orbital) analysis of NBD–Cl has been undertaken. Its utility as […]

4-Chloroaniline (4-ClA) is a chlorinated aromatic amine that is formed as an intermediate during the microbial decomposition of phenylurea and phenylcarbamate. The formation of various oligomers by polymerization of 4-ClA with guaiacol in an aqueous solution containing oxidoreductases has been reported. 4-ClA undergoes decomposition via oxidation by fusarium oxysporum, a soil fungus.

4-Chloroanisole is an electron-rich chloroarene. It undergoes Ullmann-type homocoupling catalyzed by in situ generated Pd colloids. Reaction of 4-chloroanisole with Cu(II)-smectite in n-hexane, carbon tetrachloride or dichloromethane has been studied. The nucleophilic photosubstitution reactions, photocyanation and photohydrolysis of 4-chloroanisole has been studied by time resolved spectroscopy.
