“…Single crystal X-ray diffraction of PTD PTD was synthesized following the procedure reported by Gelinas et al 29 A suitable specimen for single crystal X-ray diffraction (SC-XRD) experiments was obtained by slow evaporation of a solution of PTD in chloroform. Room-temperature SC-XRD measurements reveal that PTD crystallizes in an orthorhombic cell in the Pbca space group with lattice parameters:…”

Highly Dispersed Ultrafine Palladium Nanoparticles Enabled by Functionalized Porous Organic Polymer for Additive‐Free Dehydrogenation of Formic Acid

Formic acid (FA) is one of the most favorable chemical hydrogen storage materials for renewable energy transformation, the development of efficient heterogeneous catalysts for ultraclean H2 generation from FA in the absence of any alkalis or additives under mild conditions remains a major challenge. Here, we present a porous organic polymer containing triphenylamine (TPA) and 2,6‐bis(1,2,3‐triazol‐4‐yl)pyridyl (BTP) units (TB‐POP). The ultrafine palladium nanoparticles (NPs) with an average size of 1.5±0.6 nm can be facilely generated using convenient methods and are uniformly dispersed over the TB‐POP support. TPA and BTP units are homogeneously arranged in the host framework of TB‐POP; they serve as effective alternatives of basic sites to deprotonate FA into formate intermediates. Pd@TB‐POP has demonstrated remarkable catalytic activity and high selectivity in additive‐free dehydrogenation of aqueous FA solution. The value of initial turnover frequency (TOF) at 50 °C is as high as 1344 h−1. In sharp contrast, the use of sodium formate as an additive in the catalytic system results in the decrement of catalytic activity. The ultrafine palladium NPs are effectively immobilized during dehydrogenation of FA, and no aggregation of palladium NPs is observed after consecutive catalytic runs.

Implications of the final ring closure to 10b-aza-10c-borapyrene for aryl–alkyne ring-closing mechanisms

Through a combined computational and isotopic labeling study, it has been observed that the activation energy for the aryl–alkyne ring closure of the azaborine containing 4-ethynyl-4a-aza-4b-boraphenanthrene is dramatically lower, and it appears to proceed via an alternate mechanism than that of its hydrocarbon analog. This catalyst-free reaction proceeds at modest reaction conditions compared with traditional pyrolytic synthetic methods and holds promise for the efficient construction of fused ring systems containing azaborine functional groups that may not be accessible in the purely hydrocarbon form.
