DOI: 10.1002/cctc.201801343
Abstract: The transfer hydrogenation (TH) of several aldimines has been studied using [RuCl(p‐cymene)(dmbpy)]BF4, 1, (dmbpy=4,4′‐dimethyl‐2,2′‐bipyridine) as a precatalyst. Both neat water and a biphasic water/toluene mixture (w/t) have been successfully used as solvents. In the w/t… read more here.

DOI: 10.1002/ecy.2211
Abstract: The deuterium ratio (2 H/1 H) in tissue is often used to estimate terrestrial subsidies to aquatic consumers because of strongly differentiated values between terrestrial and aquatic primary producers. However, quantitative deuterium-based analyses of terrestrial… read more here.
