“…Quinoline-based quaternary salts have attracted the attention of researchers in different areas of organic chemistry for their relevant applications such as DNA-intercalators (Mazzoli et al, 2011), fluorescent pH-sensors (Badugu et al, 2005a), fluorescent labels for antibiotics (Zeng et al, 2010), proteins (Hong et al, 2004), heparin (Sauceda et al, 2007), sacharides (Badugu et al, 2005b), fluorescent probes for fluoride and cyanide ions (Badugu et al, 2004) and nucleotides (Dorazco-Gonzá lez et al, 2014). These cationic organic compounds are probably the most used fluorescent sensors for chloride ions in aqueous media (Bazany-Rodríguez et al, 2015) and intracell samples (Baù et al, 2012). On the other hand, benzamide compounds are used as intermediaries for the synthesis of species with biological activity such as 1,4-benzodiazepinones, thiazoles and oxazoles (Majumdar & Ganai, 2011;Majumdar & Ghosh, 2013;Majumdar et al, 2012) and bicyclic Nheterocycles and nitrogen-rich medium-size heterocycles (Mondal et al, 2012;Zeni & Larock, 2006;Ohta et al, 2008;Majumdar et al, 2008;Raju et al, 2009;Evdokimov et al, 2011).…”
