Abstract: By utilizing the characteristic features of vinylsulfides, 2-(alkylthio)allyl silyl ethers were designed as efficient ene substrates, and their use led to exploration of general carbonyl and imine ene reactions. By using 3-(alkylthio)-2-siloxyallyl acetates, a useful [3 + 2]cyclopentane annulation methodology was developed. Further, a tandem CC bond formation/cleavage methodology was ...

Tripodal pyrrole imine and amide ligands provide platforms for combined primary and secondary coordination sphere interactions in square planar Pd and Cu, and octahedral Ti complexes.

Copper-based metal-organic framework (Cu3(BTC)2(H2O)3]n⋅nH2OMeOH (HKUST-1) has been subjected to thermolysis under air atmosphere at different temperatures ranging from 100 300 °C. This treatment produces the partial removal of ligands, generation structural defects and additional porosity in a controlled way. The resulting defective materials denoted according literature as quasi-MOFs, were su...

Dicarbonyls are known to be important precursors of so-called atmospheric brown carbon, significantly affecting aerosol optical properties and radiative forcing. In this systematic study we report the formation of light-absorbing nitrogen containing compounds from simple 1,2-, 1,3-, 1,4-, and 1,5-dicarbonyl + amine reactions. A combination of spectrophotometric and mass spectrometric techniques...

This work is investigating the chemical grafting on Ti surface of a polymer/calcium phosphate coating of improved adhesion for enhanced bioactivity. For this purpose, a whole new methodology was developed based on covalently attaching a hyperbranched poly(ethylene imine) layer on Ti surface able to promote calcium phosphate formation in a next deposition stage. This was achieved through an inte...

A series of fullerene substituted phenylalanine derivatives have been prepared by the condensation of 1,2-(4'-oxocyclohexano)fullerene with ester or Boc protected (4-amino)phenylalanine, H(2)NC(6)H(4)CH(2)CH(COR(1))(NHCOR(2))(where R(1) = OMe, R(2) = Me; R(1) = OH, R(2) = Me, O(t)Bu). Conversion of the imine to the corresponding amine is achieved by di-acid catalyzed hydroboration. Reaction of ...

Generation of azomethine imine and its scope in regioselective 1,3-dipolar cycloaddition (DC) of imine with PhIO toward highly substituted Delta(2)-1,2,4-triazoline, 1,2,4-triazole, and their fused, chiral, and sugar-based analogues are demonstrated.
