Gender: Dealing with HBr «on:April 30, 2018, 07:21:39 PM » Hey there, The reaction I'm doing is creating a large amount of HBr over a period of hours. I'm wondering if there is an efficient way of dealing with it as it is corroding my fume hood extraction system. I've ...
Stereoselective reactionHydrohalogenation of alkynes is one of the fundamental reactions in organic chemistry, as described in textbooks that begins from old time as Reppe's chemistry. This method, which directly affords haloalkenes in a single step, is attractive from both industrial and academic ...

Under the catalysis of 1 mol% of Br 2 or HBr at room temperature, indoles undergo a rapid reaction with 3-hydroxy-3-(indol-3-yl)indolin-2-ones to give asymmetric 3,3-di(indol-3-yl)indolin-2-ones with high efficiency and wide substrate scope. This is a ra
The reaction of the mononuclear complex [Cr(dpa)(ox)2]−(dpa = 2,2-dipyridylamine) with Ag+ in aqueous solution affords the two-dimensional compound {Ag3(H2O)[Cr(dpa)(ox)2]3}n·2nH2O (1) whose structure has been determined by single-cr... CY Vivas,Delgado, Fernando S,Ruiz-Prez...
The mould metabolite culmorin has been degraded in a stepwise manner to tetrahydroeucarvone and converted in a simple reaction sequence to enantiolongiborneol. These and related studies have shown that culmorin is 2,6,6,9-tetramethyltric... DHR Barton,NH Werstiuk - 《Journal of the Chemical...
However, transition metal catalysts are commonly expensive and it may also be hard to be removed from the reaction substrates, which might lower the purity of the products. Therefore, the new catalysts with no transition metal, will be of great value. Our research was initially inspired by the...
