write three reaction in the synthesis of alcohols, aldehydes and ketones using the reducing agent LiAlH4
Incorporate the protection and deprotection of ketones, aldehydes, and alcohols in syntheses. 6. The following reaction will not go as protection/deprotection that will improve the outcome of the synthesis planned. Devise a plan for NaSCH3 H3CS Br
Give a balanced equation for the reaction that includes both the oxidizing agent (benzil) and reducing agent (NaBH4). In other words I do not want to see 4 R2C=O. Give a brief definition/explanation of reduction in terms of gain/loss of hydrogens, oxygen, and electrons. Sodium borohydride can be used in ethanol solutions to rapidly reduce aldehydes and ketones at room temperature. Even though lithium aluminum hydride (LiAlH4) is much more reactive than sodium borohydride (NaBH4) it can’t be used to reduce aldehydes...
