Synthesis of 4-(4-Hydroxyaryl)-1,3-Dithiolium Perchlorates

Abstract

4-(3,5-Dibromo-4-hydroxyphenyl)-2-(N,N-dialkylamino)-1,3-dithiol-2-ylium perchlorates have been synthesized by acid catalyzed cyclocondensation of 1-(3,5-dibromo-4-hydroxyphenyl)-1-oxaethan-2-yl dithiocarbamates. The latter compounds have been obtained from the reaction of the corresponding substituted w-bromoacetophenone with various salts of dithiocarbamic acids.

New 4-(4-Hydroxyaryl)-5-Methyl-1,3-Dithiol-2-ylidene Derivatives

“…Moreover, novel dye-sensitized solar cells based on 1,3-dithiol-2-ylidene derivatives have been recently reported [9]. For these reasons heterocyclic compounds -especially those containing sulfur -represent an important resource for the material chemistry and not only [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. An important precursor for 1,3-dithiol-2ylidene derivatives are the 1,3-dithiolium-2-yl compounds.…”

Mesoionic 4-(2-Dialkylamino-1,3-dithiol-2-ylium-4-yl)phenolates

“…In this context, a variety of acceptor units has been investigated, special attention being devoted to the nature of cationic systems. Thus, particular attention has been paid to the systems where the donor moiety is linked through a πor σ-bonded bridge to the acceptor moiety [32][33][34][35][36][37][38][39][40][41][42][43][44]. Recently, new evidences for the mesoionic character of 2-(1,3-dithiol-2-ylium)phenolates (Iasinones) have reported reported [45,46].…”
