Fe(NO₃)₃•9H₂O-Mediated Visible-Light Photocatalysis for the Nitration of Cyclobutanols: Access to Functionalized Nitrocyclobutenes

A straightforward method for the synthesis of nitrocyclobutenes derivatives from cyclobutanols with Fe(NO3)3•9H2O has been developed via visible-light photocatalytic radical addition reaction. The reaction utilizes Fe(NO3)3•9H2O as nitro source and...
