“…The photophysical and photochemical properties of Mo 0 complexes with monodentate arylisocyanide ligands were first explored nearly 40 years ago . Some 3 MLCT luminescence was indeed observed, but these complexes become substitutionally labile upon photoexcitation, thus making them unsuitable for most applications . Recently, W 0 complexes with monodentate arylisocyanides were found to be strong emitters and photoreductants, but as a 5d metal, W 0 is inherently more inert to substitution than the 4d metal Mo 0 .…”

A Molybdenum(0) Isocyanide Analogue of Ru(2,2′‐Bipyridine)₃²⁺: A Strong Reductant for Photoredox Catalysis

We report the first homoleptic Mo(0) complex with bidentate isocyanide ligands, which exhibits metal-to-ligand charge transfer ((3) MLCT) luminescence with quantum yields and lifetimes similar to Ru(bpy)3 (2+) (bpy=2,2'-bipyridine). This Mo(0) complex is a very strong photoreductant, which manifests in its capability to reduce acetophenone with essentially diffusion-limited kinetics as shown by time-resolved laser spectroscopy. The application potential of this complex for photoredox catalysis was demonstrated by the rearrangement of an acyl cyclopropane to a 2,3-dihydrofuran, which is a reaction that requires a reduction potential so negative that even the well-known and strongly reducing Ir(2-phenylpyridine)3 photosensitizer cannot catalyze it. Our study thus provides the proof-of-concept for the use of chelating isocyanides to obtain Mo(0) complexes with long-lived (3) MLCT excited states that are applicable to unusually challenging photoredox chemistry.

“…Site-specific mutagenesis was performed by the insertion of a neomycin-resistance cassette (Shaw et al, 1984) into DNA fragments subcloned into an A. tumefaciens suicide vector, p JQ200SK (Quandt & Hynes, 1993). p JQ2OOSK carries the sucrose-inducible sacB gene, whose product is lethal to Gram-negative bacteria.…”

The authors have identified a fourth flagellin gene in a 2 1 850 bp region of the Agrobacteriurn turnefaciens C58C1 chromosome containing a t least 20 genes concerned with flagellar structure, assembly and function. Three flagellin genes, f/aA, f/aB and flaC, orientated rightward, are positioned in a tandem array at the right end, with the fourth, substantially larger gene, flaD, in the opposite orientation, a t the left end. Between these lie four apparent operons, two transcribed in each direction (rnotA, f/hB leftward; f/gF, f/gB rightward) from a divergent position approx 7.5 kb from the left end. This unifies the previously published rnotA, f/gB and f/aABC sequences into a single region, also containing the homologues of f/hB, f/gF and f/i/. Site-specif ic mutagenesis of f/i/ results in a non-flagellate phenotype, while a Tn5-induced f/hB mutant possesses abnormal flagella. Mutagenesis and protein profiling demonstrate that all four flagellins contribute to flagellar structure: FlaA is the major protein, FlaB and FlaC are present in lesser amounts, and FlaD is a minor component. FlaA has anomolous electrophoretic mobility, possibly due to g I ycosy lat ion.

“…Using these gauge transformations, the (quasi) DBTs for the sAKNS hierarchy and its generalizations can be constructed, which turns out to be canonical as well. Some other topics such as iterated DBTs ,soliton solutions and nonlocal conserved charges of these hierarchies are worth further investigation [26]. We leave this work to a future publication.…”
