The invention relates to a process for preparing organic monomeric or polymeric compounds carrying tert-butyloxycarbonyl groups, wherein a monomeric or polymeric organic compound, which possesses at least one heteroatom with an acidic proton, such as an aliphatic or aromatic alcohol, an amide, imide or lactam, is reacted with di-tert-butyl dicarbonate in an inert solvent in the presence of about 0.01 to about 10 mol percent, relative to the compound to be converted, of a catalyst at a temperature from about 0.degree. to about 80.degree. C. The reaction solution can be used for further processing, or the reaction product can be isolated by evaporation of the solvent or by precipitation in water and drying. The compounds are preferably used in light-sensitive coatings.
A process for preparing organic monomeric or polymeric compounds bearing tert-butyloxycarbonyl groups, comprising the step of reacting (i) an organic compound which possesses at least one heteroatom with an acidic proton selected from the group consisting of aliphatic or aromatic alcohols, amides and lactams with (ii) di-tert-butyl dicarbonate in an inert solvent and in the presence of about 0.01 to about 10 mol percent, relative to the organic compounds to be converted, of a tertiary amine catalyst, at a temperature from about 0.degree. to about 80.degree. C.
