Methodologies Limiting or Avoiding Contamination by Organotin Residues in Organic Synthesis.

New functionalized polynorbornenes have been obtained in good yields by vinylic copolymerization of norbornene with a (norbornenyl)Sn-Bu 2 Cl monomer, catalyzed by [Ni-(C 6 F 5 ) 2 (SbPh 3 ) 2 ]. Subsequent functionalization produces a wide variety of polymers with different -SnBU 2 R groups (R=aryl, vinyl, alkynyl). The polymers can be used as R-transfer reagents in Stille couplings, thereby providing easy workup and separation of the polymeric tin byproducts from the coupling products. Tin contents of around 0.05wt % are found in the Stille products. The stannylated polymers can be recycled and reused with good efficiency.

Here we report a novel family of crystalline, supermicroporous iron(III) phosphonate nanomaterials (HFeP-1-3, HFeP-1-2, and HFeP-1-4) with different Fe(III)-to-organophosphonate ligand mole ratios. The materials were synthesized by using a hydrothermal reaction between benzene-1,3,5-triphosphonic acid and iron(III) chloride under acidic conditions (pH ≈ 4.0). Powder X-ray diffraction, N2 sorption, transmission and scanning electron microscopy (TEM and SEM) image analysis, thermogravimetric and differential thermal analysis (TGA-DTA), and FTIR spectroscopic tools were used to characterize the materials. The triclinic crystal phase [P1(2) space group] of the hybrid iron phosphonate was established by a Rietveld refinement of the PXRD analysis of HFeP-1-3 by using the MAUD program. The unit cell parameters are a = 8.749(1), b = 8.578(1), c = 17.725(3) A; α = 104.47(3), β = 97.64(1), γ = 113.56(3)°; and V = 1013.41 A(3). With these crystal parameters, we proposed an 24-membered-ring open framework structure for HFeP-1. Compound HFeP-1-3, with an starting Fe/ligand molar ratio of 3.0, shows the highest Brunauer-Emmett-Telller (BET) surface area of 556 m(2) g(-1) and uniform supermicropores of approximately 1.1 nm. The acidic surface of the porous iron(III) phosphonate nanoparticles was used in a highly efficient and recyclable catalytic transesterification reaction for the synthesis of biofuels under mild reaction conditions.

The crystal and molecular structure of 23,24-dinor-5α-cholan-12-one has been determined. Rings A, B and C have a chair conformation, ring D a half-chair conformation. All rings are trans connected. The crystal structure of the title compound confirms the link between a different kinetic behaviour during reduction of 12-oxosteroids with LiAlH 4 and a different orientation of the π system of the ketone functional group
