Upon demand, 1,3‐diamino‐propane‐triethylborane (DAPTB) is photolyzed in the presence of an acid generator such as a diphenyliodonium salt. Interestingly, triethylborane is released. In the presence of oxygen, ethyl radicals are generated and initiate an acrylate polymerization. This is the first example of a phototriggered production of a triethylborane usable in the photoinitiation of acrylate polymerizations. This approach is also worthwhile to overcome the oxygen inhibition for free‐radical polymerization processes.
