The in-line TBADT recovery proves the potential of OSN for catalyst recovery, thus helping bridge the gap between small-scale HAT transformation and their scaled-up counterparts. To further highlight the potential of this technique, a small scope for the model photocatalytic hydroalkylation was performed, reporting both the product yield for the reaction carried out with pristine TBADT and the product yield for the reaction performed with the in-line catalyst recovery configuration depicted in Scheme 1. Different electrondeficient alkenes, including esters and fumaronitrile were all good Michael acceptors, delivering good yields of the targeted products (1 to 3). Cyclopentane underwent the C-C bond forming reaction promptly, transforming unactivated alkyl substrate into targeted hydroalkylated compound (4). Esters (1,3-dioxolane and 1,4-dioxane) were used as Hdonors for the radical addition on dimethyl maleate, which afforded the targeted products (5, 6) in excellent yields. Promisingly, for all entries in the scope, the product yields are similar for to those obtained without catalyst recycling, proving the generality of our inline catalyst recycling strategy. To conclude, this work presents in-line TBADT recovery as the answer to the concerns surrounding scale-up of TBADT-catalyzed photocatalytic HAT reactions, where catalyst consumption, cost, and removal are major concerns. A suitable OSN membrane was identified, and the operating conditions and experimental design were optimized to achieve suitable catalyst and product recovery. Notably, the product yield of reactions performed with in-line catalyst recovery are comparable to those carried out with pristine catalyst, proving that not only TBADT recovery is technically feasible, but it also does not compromise reaction performance. Considering the widespread interest in decatungstate-enabled HAT photocatalysis, we expect this inline catalyst recovery protocol will be particularly useful for process chemists to reduce the overall operational cost of the scaled-up process.
