Key words

photocatalysis - alkenes - trifluoromethylation

Significance

A metal–organic layer (MOL) containing eosin Y and Fe-TPY ligands (Hf-EY-Fe), prepared according to equation 1, catalyzed the trifluo­romethylative amination (eq. 2), hydroxylation (eq. 3), or chlorination (eq. 4) of alkenes to give the corresponding products in yields of up to 95%.

Comment

Hf-EY-Fe was characterized by means of ICP-MS, TEM, AFM, HRTEM, PXRD, UV–Vis, fluorescence, XANES, XPS, and EXAFS analyses. In the trifluoromethylative chlorination of 7-bromohept-1-ene with trifluoromethanesulfonyl chloride, the catalyst was recovered and reused four times without significant loss of its catalytic activity.
