Visible-light-mediated hydrolysis of benzyl halides has been achieved that is efficiently catalyzed by metal-free catalyst rhodamine B. Benzyl bromides and chlorides can smoothly react with water to prepare a series of benzyl alcohol compounds in good yields.[a] Dr.

A novel reducing system, In(OTf) 3 /PhSiH 3 , was developed, which smoothly and effectively hydrogenates a variety of azobenzenes to hydrazobenzenes. Azobenzenes with diverse functional groups were reduced to their corresponding hydrazobenzenes in high yields. The catalytic method utilized is simple and operates under exceedingly mild conditions.
