New non-halide counter anions based ionic macromols. (IMs) were synthesized by the ionic exchange method. The mol. aggregates of the target IMs were formed in H2SO4 medium. The evolving concentrations and time showed a remarkable influence on the formation of the IMs aggregates. Copper surface could be adsorbed by the IMs, which were confirmed by the SEM as well as AFM imaging. The contacting angles suggest that the adsorption layers of the IMs on metal surface could be composed by the inner hydrophobic film and the outer hydrophilic film. The IMs-copper bonding was further demonstrated by different means including FT-IR and XPS. The electrochem. survey suggested that the IMs adsorption layers inhibited copper corrosion in H2SO4 solution, and the peak efficiency of corrosion inhibition reached over 99%. In addition, the mixed chemisorption and physisorption of the IMs to copper is reveled by the Langmuir isotherms.

A series of novel aryloxide imidazolin-2-imine bidentate neutral Pd(II) complexes with different substituents on the imidazolin-2-imine ligand were synthesized and characterized. In the single crystal X-ray diffraction anal., the complexes Pd1 and Pd2 adopted almost square-planar geometries, while Pd3 bearing the bulkier 2,6-bis(diphenylmethyl)-4-methylphenyl substituent was obtained as the allyl adducted base-free η3 coordination mode. In the presence of very low EtAlCl2 loadings (100 equivalent), these Pd(II) complexes exhibited high activity (∼106 g mol-1 h-1) and good thermal stability (up to 100°C) toward the addition polymerization of norbornene. Most importantly, these Pd(II) catalysts were able to promote the copolymerization of norbornene with 1-dodecene and 1-octadecene with high activity (>105 g mol-1 h-1) to yield high-mol.-weight (Mn up to 5.59 x 104 g mol-1) copolymers. The 1-alkene incorporation of resulting copolymers was modulated in a wide range (5.1-15.3%) by changing the comonomer feed ratio, accompanied by the control of the glass transition temperature (Tg = 231.6-309.6°C).

α-Methylene-δ-valerolactone (MVL) is a bifunctional monomer comprising of a highly stable six-membered δ-valerolactone ring and highly reactive C=C bond. Previously, the vinyl-addition polymerization (VAP) product, namely P(MVL)VAP, has been formed exclusively. In this study, this conventional chemoselectivity is reversed, wherein organic catalysts are used to enable the first ring-opening polymerization (ROP) of MVL, exclusively affording a metal-free, unsaturated polyester, namely P(MVL)ROP. This challenging goal is achieved by investigating different catalysts, initiators, and reaction conditions. In addition, the formation of two polymers, namely P(MVL)ROP and P(MVL)VAP, is easily regulated by varying the polymerization solvent. The resulting P(MVL)ROP can be easily post-functionalized to form crosslinked or sulfurized materials; notably, it can be almost completely converted into its monomer thermochem.

The synthesis of element-carbon double bonds is of great importance for the development and understanding of reactive π-bonded systems in chem. The seven-membered heterocyclic system 4b is readily made by internal C-H activation at a pendent iso-Pr Me group of the resp. [(IPr)C6F5BH]+ borenium ion. Subsequent deprotonation with the IMes carbene gives the neutral cyclic boraalkene system 5b. The B:C double bond in compound 5b adds carbon dioxide, CS2, sulfur dioxide, Ph isocyanate, an acetylenic ester or two NO mols. to give the corresponding four-membered ring annulated heterocycles. With sulfur or selenium 5b gives the resp. three-membered ring systems. N2O reacts with 5b to give a mixture of the related oxaborirane 18 and a unique [B]OH containing diazoalkane product 19.
