The present study illustrates the importance of the oxidation state of iron within the mesoporous iron trimesate [{Fe(3)O(H(2)O)(2)F(0.81)(OH)(0.19)}{C(6)H(3)(CO(2))(3)}(2)] denoted MIL-100(Fe) (MIL= Material from Institut Lavoisier) during adsorption of molecules that can interact with the accessible metal sites through π-back donation.

Cyclisation of diethyl 3-allyloxy-1-propynylphosphonates with Mo(CO)(6) under PK conditions to give 3-substituted-5-oxo-3,5,6,6a-tetrahydro-1H-cyclopenta[c]furan-4-ylphosphonate, 2a-h, in 45-88% isolated yields was done. The R groups are always syn with H(b) (where applicable). The stereochemistry was determined via both NMR and crystal X-ray analysis.

The reactions of ground-state boron atoms, B((2)P(j)), with methylacetylene, CH3CCH(X(1)A(1)), and its [D3]-substituted isotopomer, CD3CCH(X(1)A(1)), are studied under single collision conditions using the crossed molecular beam technique at collision energies of 21.6 and 21.9 kJ mol(-1), respectively. Utilizing the CD3CCH
