Reductive dechlorination of 4-chloro 3-nitro benzotrifluoride with sodium borohydride
From the time immemorial, sodium borohydride has been used for the reagent of choice for reducing various carbonyl compounds and acid chlorides in protic solvents. Over the past decades the utility of sodium borohydride has been greatly expanded and various modifications have been developed. Reductive dechlorination of aromatic halo nitro compounds have a great significance in the field of orga...
متن کاملHighly enantioselective epoxidation of 2-methylnaphthoquinone (vitamin K3) mediated by new cinchona alkaloid phase-transfer catalysts.
In the area of catalytic asymmetric epoxidation, the highly enantioselective transformation of cyclic enones and quinones is an extremely challenging target. With the aim to develop new and highly effective phase-transfer catalysts for this purpose, we conducted a systematic structural variation of PTCs based on quinine and quinidine. In the total of 15 new quaternary ammonium PTCs, modificatio...
متن کاملControlled growth and catalytic activity of gold monolayer protected clusters in presence of borohydride salts.
In the presence of large excesses of borohydride salts, gold monolayer protected-clusters can be grown to larger sizes simply by controlling the amount of reducing agent added to smaller clusters. In addition, gold monolayer clusters can be used as catalysts for reduction reactions by sodium borohydride; results suggest such catalysts have sterically constrained active sites.
متن کاملReductive Dehalogenation of a-Haloketones by Sodium Borohydride and Tin(II) Chloride in Tetrahydrofuran
The dehalogenation of a-haloketones and a-halocarbonyl compounds is an inevitable proce dure for the organic synthesis and these reductive dehalogenations have been often effected in organic syntheses. There have been various procedures for the purpose and these are obtained by zinc and acetic acid [1], sodium dithionite [2], titanium(III) chloride [3], organotin hydride [4], sodium hydrogen t...
متن کاملSodium borohydride stabilizes very active gold nanoparticle catalysts.
Long-term stable 3 nm gold nanoparticles are prepared by a simple reaction between HAuCl4 and sodium borohydride in water under ambient conditions which very efficiently catalyze 4-nitrophenol reduction to 4-nitroaniline.
