Immobilisation of photoswitchable diarylcyclohexenes synthesised via cobaltmediated Diels–Alder reaction

Zusammenfassung

Functionalised photoswitches - photochromic dithienylcyclohexenes-were prepared in two steps by a cobalt- mediated Diels-Alder reaction of internal alkynes with the isoprenylpinacolboronic ester. The three-component one-pot reaction sequence provides the photochromic dithienylcyclohexenes in up to 67% overall yield.
