Chem 2212l Experiment 7 Microwave Assisted Reduction Of Aldehydes And Pre lab i. title experiment 7: reduction of an unknown aldehyde or ketone with microwave assistance ii. introduction sodium borohydride is a useful reducing reagent, initially discovered for wartime applications, that can reduce organic carbonyl compounds. Fig 1: generic reaction scheme of aldehydes or ketones reduced by sodium borohydride. sodium borohydride was discovered in the 1940s by h. i. schlesinger for wartime applications. since its initial discovery, sodium borohydride has been used to reduce a series of organic carbonyl compounds, including aldehydes, ketones, acyl chlorides, thiol.
Lab 9 Ketone Aldehyde Post Lab Carolus Korie Garber Chem 2212l Reduction of an unknown aldehyde or ketone using sodium borohydride. Describe sodium borohydride. a gentle reducing agent used for aldehydes, ketones, acyl halides, thiol esters, and imines. what will sodium borohydride not reduce under normal circumstances. esters, amides, and carboxylic acids. in this experiment, what was sodium borohydride used to reduce. unknown aldehydes and or ketones. 2212 lab 2 acid catalyzed isomerization of carvone and carvacrol. 2212 lab 5 fischer esterification of unknown alcohol. pre lab 7 ochem 2 microwave assisted reduction of aldehydes and ketones by sodium borohydride. pre lab 6 ochem 2 synthesis of an amide from an unknown amine pre lab. acidic vs basic conditions in nucleophilic ring. Experimental procedure: obtain 0.5 g of sodium borohydride and place it into a microwave teflon vessel along with 20.0 ml 95% ethanol and a stir bar. add 2.00 ml of the unknown aldehyde or ketone assigned by your ta to the bubbling solution. seal the microwave vessel and start microwave heating using the program shown in fig 2.
