One-pot synthesis and the structure study of a new salt spiropyran of indoline series containing 2H-chromenic vinyl-3H-indolium fragment as a substituent at the position 8 are described. The structure was confirmed by the method of NMR 1H and 13C spectroscopy, IR and high-resolution mass spectrometry. The single crystals of the compound were investigated by X-ray analysis. The structure was compared with the previously known isostructural analogue [10].

In this article we describe an efficient approach for the synthesis of cyclic diaryliodonium salts. The method is based on benzyl alcohols as starting materials and consists of an Friedel-Crafts-arylation/oxidation sequence. Besides a deep optimization, particluar focusing on the choice and ratios of the utilized Bronsted-acids and oxidants, we explore the substrate scope of this transformation. We also discuss an interesting isomerism of cyclic iodonium salts substituted with aliphatic substituents at the bridge head carbon. <br>
