The target molecule is simply the oxime of benzaldehyde. Oximes can be prepared from the parent ketone or aldehyde by reaction with NH2OH.
The target molecule is benzoic acid. Carboxylic acids can be prepared from the corresponding aldehyde by simple oxidation with CrO3/H2SO4.
The target molecule is simply a cyclic acetal derived from benzaldehyde and ethylene glycol (1,2-ethanediol). Acetals can be prepared from the corresponding aldehyde by reaction with the alcohol in the presence of an acid catalyst.
The target molecule is benzyl alcohol. Primary alcohols can be prepared from the corresponding aldehyde by reduction with BH4-.
