Flowing scalable production of sulfenamides by active site-tuned lacunary polyoxometalate foams

Four transition-metal lacunary polyoxometalates (TM-LPOMs, TM = Cu, Co, Ni, and Mn) are prepared and fabricated into ultralow density LPOM-based foams (LPOMs@CMC) for the efficient flowing catalytic production of sulfenamide additives.
