Ethylene is an important plant hormone that is involved in a variety of developmental processes including agriculturally important ripening of certain fruits. Owing to its significant roles, a number of approaches have previously been developed to detect ethylene via molecular interactions. However, there are no current approaches for detection that are selective via a discrete homogeneous molecular interaction. Here we report two profluorescent chemodosimeters for the selective detection of the plant hormone ethylene. The approach consists of a BODIPY fluorophore with a pendant ruthenium recognition element based on a Hoveyda-Grubbs second generation catalysts. A marked increase in fluorescence is observed upon exposure to ethylene and selectivity is observed for ethylene over other alkenes, providing a unique approach toward ethylene detection. Imaging in live cells demonstrated that ethylene could be detected from multiple relevant sources.

The hydride transfer initiated cyclization ("HT-cyclization") of aryl alkyl ethers, which leads to direct coupling of sp3 C-H bonds and activated alkenes, is reported. Readily available salicylaldehyde derived ethers are converted in one step to dihydrobenzopyrans, an important class of heteroarenes frequently found in biologically active compounds. This process has not been previously reported, in contrast to known HTcyclizations of the corresponding fert-amines ("tert-amino effect" reactions).
