Synthesis of β-Hydroxysulfones from Sulfonyl Chlorides and Alkenes Utilizing Visible Light Photocatalytic Sequences.
The synthesis of β-hydroxysulfones from sulfonyl chlorides and styrenes in the presence of water by a visible light mediated atom transfer radical addition (ATRA)-like process utilizing fac[Ir(ppy)3] as photoredox catalyst was developed in high yields. This process could be combined with the visible light mediated synthesis of trifluoromethylated sulfonyl chlorides via an ATRA reaction between alkenes and CF3SO2Cl utilizing [Cu(dap)2Cl] as photoredox catalyst, demonstrating the possibility of sequential photoredox processes.
