Final answer:
The provided information does not match the question about synthetic conversions; correct details are needed to outline accurate synthesis pathways in organic chemistry.
Step-by-step explanation:
It appears there has been a mix-up with the questions and related information provided; the references do not match the question regarding synthetic conversions. I would be happy to help with synthetic chemistry questions, however, without the correct context or question details, providing an accurate synthesis pathway is not feasible. In synthetic organic chemistry, converting one compound to another involves understanding functional group transformations, reagents used in organic synthesis, and reaction mechanisms. Common reagents for such transformations include but are not limited to Pd/C, LiAlH4, NaBH4, and various others depending on the specific conversion required.
(a) To convert benzyl bromide to benzylamine, you can use a nucleophilic substitution reaction. By treating benzyl bromide with ammonia (NH3), the bromine will be replaced with an amino group (-NH2), resulting in the formation of benzylamine.
(b) To convert 1-bromo-2-phenylethane to 3-phenylpropan-1-amine, you can use a series of reactions. First, treat 1-bromo-2-phenylethane with sodium azide (NaN3) to form the corresponding azide compound. Then, reduce the azide group to an amine using a reducing agent like lithium aluminum hydride (LiAlH4).
(c) To convert pentanoic acid to pentan-1-amine, you can use a two-step reaction. First, convert pentanoic acid to the corresponding acid chloride by reacting it with thionyl chloride (SOCl2). Then, react the acid chloride with ammonia (NH3) to form pentan-1-amine.
