( b ) The reagent CH 3 ONH 2 is called O -methylhydroxylamine, and it reacts with aldehydes in a manner similar to hydroxylamine. ( c ) Propanal reacts with 1,1-dimethylhydrazine to yield the corresponding hydrazone. ( d ) Acid-catalyzed hydrolysis of the acetal gives the aldehyde in 87% yield. ( e ) Hydrogen cyanide adds to carbonyl groups to form cyanohydrins. ( f ) The reagent is a secondary amine known as morpholine. Secondary amines react with ke- tones to give enamines. ( g ) Migration of the alkyl group in a Baeyer Villiger oxidation occurs with retention of con f guration. 1 Peroxybenzoic acid O C 6 H 5 COOH ( R )-3-Methyl-3-phenyl-2- pentanone O H 3 C CCH 3 CH 3 CH 2 ( R )-1-Methyl-1-phenylpropyl acetate O H 3 C OCCH 3 CH 3 CH 2 HN O 1 Acetophenone Morpholine Carbinolamine
