An unusual direction of the reaction of 2-(cyclopent-2-enyl)aniline hydrochloride with dimethyldioxirane was found: the formation of two isomeric products, viz., 3- and 6-chloro-2-(cyclopent-2-enyl)anilines, was observed.

7-Bromo-, 7-phenylethynyl-, 7-azido-, 7-nitro-, and 5,7-dinitro-substituted N-acetyl-1,3a,4,8b-tetrahydrocyclopenta[b]indoles have been synthesized starting from anilines and 3-chlorocyclopentene. The NMR spectra of N-acetyl-7-nitro-1,3a,4,8b-tetrahydrocyclopenta[b]indoles displayed no signal doubling typical of the other 7-substituted derivatives.

(Chemical Equation Presented) We have developed an environmentally benign synthetic approach to nucleophilic substitution reactions of alcohols that minimizes or eliminates the formation of byproducts, resulting in a highly atom-efficient chemical process. Proton- and metal-exchanged montmorillonites (H- and Mn+-mont) were prepared easily by treating Na +-mont with an aqueous solution of hydrogen chloride or metal salt, respectively. The H-mont possessed outstanding catalytic activity for nucleophilic substitution reactions of a variety of alcohols with anilines, because the unique acidity of the H-mont catalyst effectively prevents the neutralization by the basic anilines. In addition, amides, indoles, 1,3-dicarbonyl compounds, and allylsilane act as nucleophiles for the H-mont-catalyzed substitutions of alcohols, which allowed efficient formation of various C-N and C-C bonds. The solid H-mont was reusable without any appreciable loss in its catalytic activity and selectivity. Especially, an Al3+-mont showed high catalytic activity for the α-benzylation of 1,3-dicarbonyl compounds with primary alcohols due to cooperative catalysis between a protonic acid site and a Lewis acidic Al3+ species in its interlayer spaces.

Myshko, Yu. V.,Kozlikovskii, Ya. B.,Koshchii, V. A.
, p. 731 - 735 (2007/10/02)
The reaction of aniline with 1,3-cyclopentadiene in the presence of aniline hydrochloride leads to a mixture of cyclopentyl- and dicyclopentylanilines, in which the products from ortho-alkylation of aniline predominate.The yields amounts to 95percent.
