complex [Mn(CO)5Br] was studied for the selective reduction of levulinic acid (LA) to 2-methyl-tetrahydrofuran (MTHF). We further studied the production of pyrrolidines via its reductiveamination using silanes (phenylsilane and tetramethyldisiloxane). The results showed high efficiency and selectivity for this reaction leading to high yields using mild reaction conditions.

N-butyl-4-pentenaminyl radical and the N-butyl-4-pentenaminium cation radical were studied. The radicals were produced in chain reactions from the same N-hydroxypyridine- 2-thione carbamate precursor. Rate constants for cyclization of the aminyl radical and ring opening of the product thus formed at 50 °C were determined. Cyclizations of the aminium cation radical, formed by protonation of the aminyl radical, were
