Other functional groups may be present in acetals or ketals prepared by these procedures. Some of these groups are keto, e.g., phenyl-glyoxal diethyl acetal carbethoxyl, e.g., ethyl acetoacetate ethylene ketal amino, e.g., /0-diethylaminopropyl methyl ketone ethylene ketal and nitro, e.g., m-nitrobenzaldehyde dimethyl acetal.
