ISOPROPYL THIOCYANATE [Thiocyanic Acid, Isopropyl Ester]
A Publication of Reliable Methods for the Preparation of Organic Compounds Working with Hazardous Chemicals The procedures in Organic Syntheses are intended for use only by persons with proper training in experimental organic chemistry. All hazardous materials should be handled using the standard procedures for work with chemicals described in references such as "Prudent Practices in the Laboratory" (The National Academies Press, Washington, D.C., 2011; the full text can be accessed free of charge at http://www.nap.edu/catalog.php?record_id=12654). All chemical waste should be disposed of in accordance with local regulations. For general guidelines for the management of chemical waste, see Chapter 8 of Prudent Practices. In some articles in Organic Syntheses, chemical-specific hazards are highlighted in red “Caution Notes” within a procedure. It is important to recognize that the absence of a caution note does not imply that no significant hazards are associated with the chemicals involved in that procedure. Prior to performing a reaction, a thorough risk assessment should be carried out that includes a review of the potential hazards associated with each chemical and experimental operation on the scale that is planned for the procedure. Guidelines for carrying out a risk assessment and for analyzing the hazards associated with chemicals can be found in Chapter 4 of Prudent Practices. The procedures described in Organic Syntheses are provided as published and are conducted at one's own risk. Organic Syntheses, Inc., its Editors, and its Board of Directors do not warrant or guarantee the safety of individuals using these procedures and hereby disclaim any liability for any injuries or damages claimed to have resulted from or related in any way to the procedures herein. -

Recent Advances in the Synthesis of Five- and Six-Membered Selena
290 RECENT ADVANCES IN THE SYNT HESIS OF FIVE - AND SIX - MEMBERED SELENA - HETEROCYCLES DOI: http://dx.medra.org/ 10.17374/targets.2021.24.290 D amiano Tanini * , Antonella Capperucci Department of Chemistry “Ugo Schiff ”, Università di Firenze , Via della Lastruccia 3 - 13, 50019 Sesto Fiorentino (Firenze ) , Italy (e - mail: [email protected] ) Abstract. Organoselenium compounds play an increasingly important role in chemistry and biochemistry. Amongst the wide variety of selenium - containing systems, selena - heterocycles are versatile derivatives with broad applications in organic synthesis, catalysis, medicinal chemistry, and biology. In this context, taking into account the poor stability of most selenylating reagents or intermediates , the developm ent of simple, mild and ver satile synthetic methodologies towards functionalised selena - heterocycles remains an attractive yet challenging topic . This chapter will be focusing on recent advances on the synthesis of different classes of selenium - containing five - and six - member ed ring systems. Contents 1. I ntroduction 2. S ynthesis of heterocyc lic systems containing selenium 3. S ynthesis of heterocyclic systems containing selenium and nitrogen 4. S ynthesis of heterocyclic systems containing selenium and other heteroatoms (O, S, P) 5. C onclusion s and future outlook Acknowledgement s References 1. I ntroduction Selenium - containing small molecules occupy a central position in chemical science , with different application s in organic synthesis, material sciences and polymer chemistry . 1,2,3 Organoselenides are often employed as synthetic intermediates, ligands, and catalysts. 4,5,6,7 Furthermore, owing to their antioxidant, enzyme modulator, and anticancer properties, selenium - containing organic molecules play an increasingly important role in medicinal chemistry and biology. -

Sodium Gluconate and Potassium Gluconate As Substitutes for Sodium Chloride in Breadmaking
Food Sci. Technol. Res., 8 (1), 75–79, 2002 Sodium Gluconate and Potassium Gluconate as Substitutes for Sodium Chloride in Breadmaking Hiroyuki TAKANO1 and Ryouko KONDOU2 1National Food Research Institute, Tsukuba Science City, Ibaraki, 305-8642, Japan 2Fujisawa Pharmaceutical Co., LTD., 5-2-3 Tokodai, Tsukuba, Ibaraki, 300-2698, Japan Received September 5, 2001; Accepted November 30, 2001 Sodium gluconate (Na-gluconate) and potassium gluconate (K-gluconate) were used as NaCl substitutes in bread- making to determine their potential usefulness in preparing reduced-sodium bread and non-sodium bread. Replace- ment of 75% of the NaCl by Na-gluconate and of 50% by K-gluconate had no effect on rheological properties of dough as measured by Brabender Extensograph. Replacement of 100% of the NaCl by either Na-gluconate or K-glu- conate resulted in decreased resistance to extension, but the decreased resistance to extension had no effect on dough handling properties. Expansion of white bread dough (5% sugar, flour weight basis) increased with the proportion of NaCl replaced by Na-gluconate or K-gluconate. The patterns of carbon dioxide production during fermentation of non-sugar bread dough showed that as the proportion of Na-gluconate or K-gluconate increased, the time required to complete fermentation decreased, and the fermentation pattern showed a gradual resemblance to that seen in non- sugar bread dough without NaCl. In white bread, complete replacement of NaCl (2%, flour weight basis) by Na-glu- conate or K-gluconate did not cause a difference in loaf volume, nor did it have any significant effect on overall desir- ability. -
