The reaction of 1-nitro-2-phenylethenes (β-nitrostyrenes) with aqueous titanium(III) chloride afforded substituted pyrroles in addition to the expected reduction products, oximes and carbonyl compounds. 2-Substituted 1-nitro-2-phenylethenes yielded divinylamine derivatives instead of pyrroles.The reaction mechanism has been rationalized by taking account of the electron transfer from titanium(III) species to the nitro olefines, followed by protonation, dimerization, cyclization, and/or hydrolysis.

Reactions of substituted nitrostyrenes with aqueous titanium trichloride afforded pyrroles, carbonyl compounds, and oximes.In some instances, divinylamines were produced as well.The reaction mechanism is rationalized taking account of electron transfer to nitroethylenes from Ti(III), followed by protonation, dimerization, cyclization, and hydrolysis.
