Procedure Synthesis of 1 Bromobutane - Scribd

The product shown can be prepared from acetaldehyde (ethanal) by addition of the Wittig reagent prepared from 1-bromobutane; therefore, the desired product can be prepared by reduction of butanoic acid to the alcohol, conversion of the alcohol to 1-bromobutane using PBr₃, conversion of this to a Wittig reagent and reaction with acetaldehyde.The target molecule is a ketone and two carbons have been added to the carbon chain.

Synthesis of 1-bromobutane Essays

The required alcohol can be prepared from acetaldehyde (ethanal) by addition of the Grignard reagent prepared from 1-bromobutane; therefore, the desired product can be prepared by reduction of butanoic acid to the alcohol, conversion of the alcohol to 1-bromobutane using PBr₃, conversion of this to a Grignard reagent, reaction with acetaldehyde to give the alcohol, and finally, oxidation to give the ketone.

The skill of organic chemists is such that very complicated naturally occurring molecules can be synthesised in the laboratory by amazing multi-stage preparations from indigo like dyes to chlorophyll.
