Abstract
The preparation of 1,3-dithiolanium salts from 1,2-ethanedithiol and carboxylic acid chlorides, the subsequent condensation of which with aromatic o-hydroxy aldehydes leads to spiropyrans of the dithiolane series, is described. The PMR spectra were studied, and the photochromic properties are discussed.
