Oxidomolybdenum(VI) complexes with aminoalcohol bis(phenolate) [O,N,O,O′] ligands: Synthesis and catalytic studies
2012
Abstract Oxidomolybdenum(VI) complex [MoOCl(Ln)] with a tetradentate O3N-type aminoalcohol bis(phenol) was prepared as two separable isomers. These complexes can catalyse the epoxidation of cis-cyclooctene and sulphoxidation of tolyl methyl sulphide as well as the oxotransfer reaction between PPh3 and DMSO.
Imidotungsten(VI) complexes with chelating phenols as ROMP catalysts
2011
Abstract Tungsten(VI) complexes of the type [W(NPh)Cl3(L)] (L = chelating phenolate) were studied as catalyst precursors for ROMP of 2-norbornene, dicyclopentadiene and 5-vinyl-2-norbornene. These compounds form active catalysts when treated by ethyl magnesium bromide. Moreover, polymerisations can be run under ambient atmosphere without complicated inert atmosphere techniques. Synthesis and crystal structure of a new precursor complex [W(NPh)Cl3(LS)] (LS = 2,4-di-tert-butyl-6-(phenylthiomethyl)phenolate) are also described.
Physical Activity from Childhood to Adulthood and Cognitive Performance in Midlife
2019
Introduction: Physical activity (PA) has been suggested to protect against old-age cognitive deficits. However, the independent role of childhood/youth PA for adulthood cognitive performance is unknown. This study investigated the association between PA from childhood to adulthood and midlife cognitive performance. Methods: This study is a part of the Cardiovascular Risk in Young Finns Study. Since 1980, a population-based cohort of 3596 children (age, 3–18 yr) have been followed up in 3- to 9-yr intervals. PA has been queried in all study phases. Cumulative PA was determined in childhood (age, 6–12 yr), adolescence (age, 12–18 yr), young adulthood (age, 18–24 yr), and adulthood (age, 24–37…
