Abstract
The first example of the synthesis of allylic sulfones through synergistic photoredox and tertiary amine catalysis, starting from MBH acetates, DABCO·(SO<sub>2</sub>)<sub>2</sub> and 4-substituted Hantzsch esters or potassium alkyltrifluoroborates <italic>via</italic> a radical pathway, is reported.
