In water and wine: Chromofluorogenic detection of the sulfite anion in pure water was accomplished by using a new hybrid organic-inorganic material that contained a probe entrapped in hydrophobic biomimetic cavities. This material was used for the detecti

Two types of pyridinium betaine dyes, 4-phenolates and 2-phenolates, which have a chromophore either of ET-30 type or the stilbazolium betaine type, have been synthesized.Both types of dyes sho

Electrophilic diazoalkane substitution of the diazo esters 7a and b with 2,4,6-trimethylpyrylium tetrafluoroborate (6a) results in the formation of the 4-(diazomethyl)-4H-pyrans 8a and b as well as the 1H-1,2-diazepines 13a and b.The latter are formed by
Δ3-DIHYDROPYRANS AND TETRAHYDROPYRANS BY REDUCTION OF PYRYLIUM SALTS WITH SODIUM BOROHYDRIDE IN ACETIC ACID

The major reduction products with triacetoxyborohydride (NaBH4 in AcOH) of 2,4,6-trisubstituted pyrylium salts bearing alkyl substituents in the 2- and/or 6-position are the Δ3-dihydropyrans with cis 2- and 6-substituents and all-cis-2,4,6-trisubstituted tetrahydropyrans. Δ3-dihydropyrans are shown to be formed via 2H-pyrans by a 1,4 reduction while tetrahydropyrans result from 4H-pyrans by reduction of both enol-ether double bonds.
