Sodium borohydride acted as the reducing agent although there could have been to equation 1, where it was shown that the limiting reagent was benzil due to. Sodium Borohydride Reduction of Benzoin. Introduction. The most . Benzoin. 1, 2-diphenylethane-1,2-diol. Part I: Procedure for the Reduction of Benzoin. 1.
chemistry experiment: Benzoin can be reduced with reagents such as NaBH4. What Stereochemical Products Are Possible If You're Starting With An. Answer to Benzoin can be reduced with reagents such as NaBH4. What stereochemical products are possible if you are starting with a.
Although not as powerful as lithium aluminum hydride (LiAlH4), it is very effective for the reduction of aldehydes and ketones to alcohols. For our purposes, sodium borohydride is really useful for one thing: it will reduce aldehydes and ketones. The mechanism of the reaction of. We use smaller (and much cheaper) hydride sources for reduction reactions in the laboratory. One of the most common hydride reagents is sodium borohydride, .
