Published: May 2012

We report a convenient and smooth protocol for the high-yielding synthesis of a triphosphane and an iso-tetraphosphane from a readily accessible tri(pyrazolyl)phosphane. The products are obtained from a one-pot reaction at room temperature and form complexes with the Fe(CO)(4)-fragment.

Structure of exonuclease VII.

Article Synopsis
  • Exonuclease VII (ExoVII) is an important bacterial enzyme involved in DNA processing and repair, particularly for single-stranded DNA and protein-DNA crosslinks.
  • Recent cryoelectron microscopy (cryoEM) studies reveal the complex structure of ExoVII, which consists of an elongated XseA·XseB holo-complex with distinct subunits and unique folding patterns.
  • The study suggests that the architecture of ExoVII influences how it interacts with substrates, indicating an evolutionary link to other DNA repair nucleases that manage similar types of DNA damage.

Doubly Threaded Slide-Ring Polycatenane Networks.

Crosslinking in polymer networks leads to intrinsic structural inhomogeneities that result in brittle materials. Replacing fixed covalent crosslinks with mobile ones in mechanically interlocked polymers (MIPs), such as in slide-ring networks (SRNs) in which interlocked crosslinks are formed when polymer chains are threaded through crosslinked rings, can lead to tougher, more robust networks. An alternative class of MIPs is the polycatenane network (PCN), in which the covalent crosslinks are replaced with interlocked rings that introduce the unusual catenane's mobility elements (elongation, rotation, and twisting) as connections between polymer chains.

Mesoionic dithiolates [(MIDt )Li(LiBr) (THF) ] (MIDt ={SC(NDipp)} CAr; Dipp=2,6-iPr C H ; Ar=Ph 3 a, 3-MeC H (3-Tol) 3 b, 4-Me NC H (DMP) 3 c) and [(MIDt )Li(THF) ] (4) are readily accessible (in≥90 % yields) as crystalline solids on treatments of anionic dicarbenes Li(ADC ) (2 a-c) (ADC ={C(NDipp) } CAr) with elemental sulfur. 3 a-c and 4 are monoanionic ditopic ligands with both the sulfur atoms formally negatively charged, while the 1,3-imidazole unit bears a formal positive charge. Treatment of 4 with (L)GeCl (L=1,4-dioxane) affords the germylene (MIDt )GeCl (5) featuring a three-coordinated Ge atom.

Pillared paddle-wheel-based metal-organic framework (MOF) materials are an attractive target as they offer a reliable method for constructing well-defined, multifunctional materials. A drawback of these materials, which has limited their application, is their tendency to form catenated frameworks with little accessible volume. To eliminate this disadvantage, it is necessary to investigate strategies for constructing non-catenated pillared paddle-wheel MOFs.

Two metal-organic frameworks (MOFs) made of indium and 1,3,5-tris(4-carboxyphenyl)benzene (H3btb) and having a layered structure have been synthesized under solvothermal conditions: [In(btb)(H2O)(DMF)]·L (InPF-50) and [In2(btb)2Cl2]2-·[(CH3)2NH2]22+·L (InPF-51). The structures of both materials have been determined by single crystal X-ray diffraction. The synthetic study which has been carried out demonstrates the influence of the selected indium salt in obtaining each MOF.
