Heteroaryl-linked norbornadiene dimers with redshifted absorptions
Development of Molecular Solar Thermal (MOST) systems for harvesting and storing solar energy is based on molecularphotoswitches that undergo photoisomerizations to metastable isomers. One challenge is to achieve low-molecular weight molecules that absorb at sufficiently long wavelengths to match the solar spectrum. Here we show that this can be achieved by linking two norbornadiene (NBD) photoswitches
We present herein the regioselective hydration of electron-rich aryl-alkynes in presence of a Schrock-type molybdenum alkylidene catalyst. The structures of the obtained ketones were confirmed by NMR spectroscopy and HRMS as well as by single-crystal X-ray diffraction. We found out that in our conditions the hydration reaction is efficient only for aryl-alkynes and their reactivity is highly dependent on the electronic nature of the substituents on the aryl group.
