Synthesis of benzofurans and benzopyrans

, 2002
Syntheses of 2,3-dihydrobenzofurans and 3,4-dihydrobenzopyrans normally involve several stages, therefore efficient syntheses of these compounds are desirable. A number of 3,4-dihydrobenzopyrans derivatives were prepared in one pot syntheses. The reaction is thought to proceed through cation intermediates, involving allylic cations generated by the ...

Spiropyran modified microfluidic chip channels for photonically controlled sensor array detection of metal ions [PDF]

, 2008
Microfluidic chips are particularly attractive for analytical purposes because they provide a convenient small platform for rapid analysis and detection.1 Furthermore, spiropyrans dyes can be used as photonically controlled, self-indicating molecular ...
