e. The rates of polymerization depended on several factors such as the amounts of initiator, copper bromide, and ligand with respect to the monomer concentration. From the kinetic plots, the polymerizations showed first-order kinetics with respect to the monomer concentration, and the typical rate of polymerization is on the order of 10-5 s-1. The photoconducting properties of the polymers were studied
Ruthenium <i>p</i>-cymene complexes with α-diimine ligands as catalytic precursors for the transfer hydrogenation of ethyl levulinate to γ-valerolactone
spectroscopy; in addition, the structure of [1]NO3 was ascertained by an X-ray diffraction study. Compounds [1–4]NO3, [4]PF6 and [4]BPh4 were investigated as catalytic precursors in the transferhydrogenation reaction of ethyllevulinate to γ-valerolactone in isopropanol solution under microwave irradiation. [4]BPh4 was revealed to be the best catalytic precursor, affording γ-valerolactone in 62% yield under optimized
