Synthesis and characterisation of new sulfonamide chalcones containing an azo group

WOS: 000435470600010The synthesis and characterisation of a new type of chalcone bearing a -N=N- bond is reported using an environmentally benign approach. The synthesis consists of two steps. (E)-4-((5-acetyl-2-hydroxyphenyl)diazenyl) benzenesulfonamide was synthesised by an easy structural modification of sulfanilamide. The key step then involved the solvent-free Claisen-Schmidt condensation of benzaldehydes to form the chalcones. The structures of all compounds were confirmed by FTIR, NMR and MS spectroscopy.Scientific and Technological Research Council of Turkey (TUBITAK)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [115Z078]We are indebted to the Scientific and Technological Research Council of Turkey (TUBITAK, Grant No. 115Z078) for their financial support for this work

The mutually reinforcing relation between international migration of highly educated labour force and economic crisis: the case of Greece

Although several studies aim at analysing the causes and impacts of the current economic crisis, especially involving the case of Greece, the role that highly educated population holds has not received wider attention. Based on an examination of both secondary data on the Greek economy/labour market and primary data collected by a survey that included 1821 graduates, this paper shows that underutilization of highly educated population harmed the competitiveness of the Greek economy, a factor which has significantly contributed to the creation of the current debt crisis and fostered the migration of graduates
