During photodecomposition and thermal decomposition in hydroxyl-containing media (alcohols, water) o-naphthoquinone diazides in electronically excited and vibrationally excited states eliminate nitrogen, forming the corresponding ketocarbenes.The singlet ketocarbenes undergo intramolecular transformation (with ring contraction and the formation of 3-indenecarboxylic acid or its esters) and intermolecular transformation, forming 1,2-hydroxyalkoxynaphthalenes in reaction with alcohols.The triplet ketocarbenes undergo intermolecular transformations, forming 1- or 2-hydroxynaphthalenes.The composition and ratio of the final products from the decomposition of o-naphthoquinone diazides in alcohols depend significantly on the nature of the alcohol, the presence of oxygen, the presence of radical acceptors, and the spectral composition of the exciting light.
