A simple and catalyst‐free strategy was developed for the synthesis of unsymmetrical thiosulfonates using readily available DABCO⋅(SO 2 ) 2 as a solid and bench‐stable sulfur dioxide surrogate. The corresponding thiosulfonates were obtained through a radical pathway with good functional group tolerance. This strategy offers a promising synthesis method for the construction of diverse and useful thiosulfonates in the field of synthetic and pharmaceutical chemistry and extends the number of still limited sulfur dioxide fixation strategies.
