Synthesis of 2-aminobenzo[b]thiophenes from 4-(2-haloaryl)-1,2,3-thiadiazoles
Androsov,Popova,Petrov,Ponyaev
, p. 2405 - 2408 (2014)
A new approach to the synthesis of 2-aminobenzo[b]thiophenes was developed on the basis of reaction of 4-aryl-1,2,3-thiadiazoles with amines in the presence of potassium carbonate. The effect of the nature of substituent in the benzene ring of the starting 4-aryl-1,2,3-thiadiazoles on the structure of the final product was studied.

A Convenient Approach to 2-Aminobenzo[b]chalcogenophenes Based on Copper-Catalyzed Transformation of 4-(2-Bromophenyl)-1,2,3-chalcogenodiazoles in the Presence of a Base and Amines
Popova,Lyapunova,Petrov,Panikorovskii,Androsov
, p. 689 - 699 (2018/06/14)
The reactions of 4-(2-bromophenyl)-1,2,3-thia-and -selenadiazoles with amines in the presence of potassium carbonate and copper(I) iodide afforded 2-aminobenzo[b]chalcogenophenes. The corresponding thiaand selenamides, prepared by interaction of 4-(2-brom

, p. 2238 - 2242 (2014/04/17)
The chemoselective reduction of several structurally diverse compounds containing carbonyl groups was achieved in the presence of low-valent titanium reagents. This novel synthetic method provides easy access to highly selective reduction of carbonyl groups, and possesses several advantages including one-step procedure, convenient manipulation, good to excellent yields, and short reaction times.
Ultrasound-mediated willgerodt-kindler reactions: Non-thermal synthesis of thioacetamides
Mojtahedi, Mohammad M.,Alishiri, Tooba,Abaee, M. Saeed
experimental part, p. 1910 - 1915 (2011/10/08)
Non-thermal, solvent-free condensation of several aryl methyl ketones with amines and elemental sulfur is efficiently conducted using ultrasonic irradiation within short time periods. Consequently, various thioacetamides are conveniently synthesized. Simi
