Application of Green Chemistry in the Synthesis of Thiopyran Derivatives
An efficient synthesis of 2H-thiopyran derivatives via three-component reaction of alkyl propiolate, benzoyl isothiocyanate or its derivatives and alkyl bromides in the presence of triphenylphosphine in water at 80o C without using any catalyst in water is described. The method offers several advantages including high yields of products and an easy work-up procedure.

سنتز سبز نانوذرات فلزی (nps) درسالهای اخیر توجه بسیارزیادی را به خود جلب کرده است. زیرا این پروتوکل کم هزینه وسازگار با محیط زیست از روش های استاندارد سنتز. در این پایان نامه ما گزارش میکنیم یک روش ساده و سازگار با محیط زیست برای سنتز نانوذرات نقره با استفاده از محلول آبی عصاره گیاه allium iranicum به عنوان یک عامل کاهش دهنده ی طبیعی. نانو ذرات نقره مشخص شد با استفاده از تکنیک های uv-visible، x...
Biotechnology and Green Chemistry
White biotechnology can be regarded as applied biocatalysis, with enzymes and microorganisms, aiming at industrial production of bulk and fine chemicals to food and animal feed additives. In its turn biocatalysis has many attractive features in the context of greenchemistry: mild reaction conditions (physiological pH and temperature); environmentally compatible catalysts and solvent (often wate...
متن کاملGreen chemistry and workers.
What follows is a summary of remarks presented by panelists participating in a workshop entitled, “What Green Chemistry Means to Workers.” The session examined the connection between green jobs—including those connected to the emerging field of green chemistry—and occupational, public, and environmental health. It was coordinated by Paul Renner, associate director of the Labor Institute, in col...
متن کاملGreen chemistry.
Gilbert's chemistry sets, those that many of today's practicing chemists received as children, proved to be the spark that ignited many a lifelong exploration of the wonders of chemistry. While DuPont was espousing its contributions to the world with its motto, "Better living through chemistry," children were using the popular Gilbert's chemistry sets to perform the simplest experiments and vie...
