An Efficient Method for the Chemoselective Synthesis of Acylals from Aromatic Aldehydes Using Bismuth Triflate
Aromatic aldehydes are smoothly converted into the corresponding acylals in good yields in the presence of 0.10 mol% Bi(OTf)3oxH20. Ketones are not affected under the reaction conditions. The highly catalytic nature of bismuth triflate and the fact that it is relatively non-toxic, easy to handle and insensitive to small amounts of air and moisture makes this procedure especially attractive for ...
متن کاملRecent Advances in Bismuth-Catalyzed Organic Synthesis
Abstract: Bismuth(III) compounds (BiX3, X = Cl, Br, NO3 and OTf etc.) are moistureand air-tolerant Lewis acids, which have been widely applied as green catalyst in diverse organic synthesis in the past few years. This review illustrates significant advances in this field over recent five years, and mainly focuses on the bismuth-catalyzed formation of carbon-carbon, carbon-nitrogen, carbon-sulfu...
متن کاملApplications of bismuth(III) compounds in organic synthesis.
This review article summarizes the applications of bismuth(III) compounds in organic synthesis since 2002. Although there are an increasing number of reports on applications of bismuth(III) salts in polymerization reactions, and their importance is acknowledged, they are not included in this review. This review is largely organized by the reaction type although some reactions can clearly be pla...
متن کاملBismuth(V) reagents in organic synthesis
The concept that the valency change from BiV to Bi could be harnessed to produce a family of selective oxidants as shown to be correct. However, completely unexpected was the efficiency of Bi reagents in carrying out arylations on oxygen, carbon and nitrogen. The new arylation procedures permit the synthesis under very mild conditions of compounds only available otherwise by indirect routes. In...
متن کاملsynthesis of 3-aryl-2h-benzo[b]-1,4-oxazines in [omim]bf4 and reduction of organic compounds in methylimidazolium formate
در این پروژه ترکیبات 3-آریل-2h-بنزو[b]-4،1-اکسازین ها از مواد اولیه تجاری مشتقات دو آمینو فنول و ?-هالو کتون های آروماتیک در مایع یونی 1-اکتیل-3-متیل ایمیدازولیوم تترا فلورو بورات([omim]bf4) سنتز شده است. این واکنش توسط باز پتاسیم کربنات محلول از طریق o-آلکیلاسیون و سپس یک واکنش آمیداسیون درون مولکولی خود بخود در مدت زمان کوتاه انجام می شود. ترکیبات 4،1-بنزوکسازین به این روش با بهره خوب تا آلی ...
