Our new, simple, and accurate colorimetric method is based on diarylethenes (DAEs) for the rapid detection of a wide range of primary and secondary amines. The probes consist of aldehyde- or ketone-substituted diarylethenes, which undergo an amine-induced decoloration reaction, selectively to give the ring-closed isomer. Thus, these probes can be activated at the desired moment by light irradiation, with a sensitivity that allows the detection of amines at concentrations as low as 10?6m in solution. In addition, the practical immobilization of DAEs on paper makes it possible to detect biogenic amines, such as cadaverine, in the gas phase above a threshold of 12 ppbv within 30 seconds.

Bromothiophene Reactions. I. Friedel-Crafts Acylation
Agua, M. J. del,Alvarez-Insua, A. S.,Conde, S.
, p. 1345 - 1347 (2007/10/02)
Friedel-Crafts acylation of 2,5-dibromo- and 2,3,5-tribromothiophenes with different acyl chlorides and anhydrous aluminium trichloride has been studied.The reaction afforded a mixture of acyl derivatives and tetrabromothiophene.The results obtained suggest a mechanism which involves the formation of bromine cations in the reaction medium.Several products obtained in this reaction are described.
