Evaluation of the prepared amino styrene derivatives for the uranium recovery from sulphate media

Simultaneous sulfonylation/arylation of styrene derivatives is achieved in a photoredox-catalyzed three-component reaction using visible light. A broad variety of difunctionalized products is accessible in mostly excellent yields and high diastereoselectivity. The developed reaction is scalable and suitable for the modification of styrene-functionalized biomolecules. Mechanistic investigations suggest the transformation to be operating through a designed sequence of radical formation and radical combination.<br>

The title compound was found to be an efficient catalyst for the selective cyclopropanation of activated olefins by ethyl diazoacetate. The cyclopropane yields range from moderate to good (75 to 95%) for activated olefins such as styrene and styrene derivatives, but are rather low (20 to 30%) for non-activated olefins such as terminal and cyclic alkenes. In the intermolecular competition, styrene was 45 times more reactive than cyclooctene. In all cases, trans (exo) cyclopropane predominated over the cis (endo) isomer.
