    Abstract Catalytic transfer hydrogenation (CTH) has recently emerged as a highly attractive approach for achieving biomass-based hydrogenation due to its avoidance of high-pressure fossil-derived H₂ and potentially reduced process costs. As numerous studies relating to the CTH of furfural (FF) have been reported recently, it is quite urgent to systematically review the recent advances, especially those in which excellent catalytic performance is achieved over simple solid acid–base catalysts. In this review, recent advances relating to the CTH of FF over heterogeneous catalysts, including metal catalysts and solid acid–base catalysts, are extensively summarized. Some potential research trends for the design of more effective catalysts and the realization of the practical industrial production of furfuryl alcohol (FFA) via CTH are also proposed. As acidic or basic sites always play an important role during biomass conversion, the great progress made in the area of CTH also provides great potential for other reactions, especially reductive functionalization.

    Abstract Highly effective and selective noble metal-free catalysts attract significant attention. Here, a single-atom iron catalyst is fabricated by saturated adsorption of trace iron onto zeolitic imidazolate framework-8 (ZIF-8) followed by pyrolysis. Its performance toward catalytic transfer hydrogenation of furfural is comparable to state-of-the-art catalysts and up to four orders higher than other Fe catalysts. Isotopic labeling experiments demonstrate an intermolecular hydride transfer mechanism. First principles simulations, spectroscopic calculations and experiments, and kinetic correlations reveal that the synthesis creates pyrrolic Fe(II)-plN

    Abstract In Bacillus subtilis the Pho regulon is controlled by a sensor and regulator protein pair, PhoR and PhoP, that respond to phosphate concentrations. To facilitate studies of the Pho regulon, a strain with an altered PhoR protein was isolated by in vitro mutagenesis. The mutation in this strain (phoR12) leads to the production of a PhoR sensor kinase that, unlike the wild-type, is functionally active in phosphate-replete conditions. The lesion in PhoR12 was shown to be a single base change that results in an Arg to Ser substitution in a region of PhoR that is highly conserved in histidine sensor kinases. While a phoR-negative mutant was unable to induce the synthesis of cell wall teichuronic acid under phosphate-limited conditions, the phoR12 mutant showed a relative increase in teichuronic acid and a decrease in teichoic acid, even under phosphate-replete conditions. The latter suggests that some or all of the genes required for teichuronic acid synthesis are members of the Pho regulon.
