Based on the information provided in manual and during the lecture, design the procedure for reduction of 2.5 mmol of vanillin by using sodium borohydride. Propose solvent, amount of reagents and solvent to be used, temperature in which reaction should be performed, time of reaction, and method of separation and purification of the product. Your procedure should be as detailed as procedures in the manual, so that any your colleague should be able to perform an experiment based on your...

Explain the following reaction questions on an analysis to the experimental procedure of borohydride reduction of a ketone. What happens if an excess of reducing agent is used? The reaction solvent is methanol? The reaction is initially carried out at less than 20C then raised to 50C. 4. upon work-up, brine is added to the reaction mix and the ethereal solution is then washed with water and brine?

hi, please help me with number 7. thank you
EXPERIMENT SEVEN SODIUM BOROHYDRIDE REDUCTION OF ACETOPHENONE HOCH, DISCUSSION The reduction of an aldehyde or ketone with sodium borohydride is straight forward and usually affords a high yield of the alcohol. The usual procedure (and the one employed in this experiment) involves dissolving the borohydride in 95% ethanol and adding the carbonyl compound to this solution. To ensure complete reaction, an excess of sodium borohydride is used. The reaction between sodium...

EXPERIMENT 11 THE MICROSCALE REDUCTION OF BENZIL WITH SODIUM BOROHYDRIDE INTRODUCTION Oxidation-reduction (redox) reactions occur in concert. One substance undergoes oxidation by donating electrons to another substance that is then reduced. In organic chemistry certain rules are followed in determining whether a particular substrate is being oxidized or reduced. Oxidation: The loss of hydrogen and/or gain of oxygen by a substrater Reduction: The gain of hydrogen and/or loss of oxygen by a substrate When an organic substrate is reduced, the...
