Pthalimide is alkylated with primary or unbranched secondary alkyl halides or sulphonate. The product thus obtained is hydrolysed to give primary amines.
Treatment of toluene with chromyl chloride in an inert solvent like or forms an insoluble complex \mathrm{C}_6 \mathrm{H}_5 \mathrm{CH}\left(\mathrm{OCrCl}_2 \mathrm{OH}\right)_2 which further on hydrolysis produces benzaldehyde.
