Commonsense Causal Reasoning between Short Texts
This paper attacks the problem of commonsense causality reasoning between short texts (phrases and sentences) using a data driven approach and proposes a novel metric to properly model the causality strength between terms. Expand
Palladium/copper-catalyzed oxidative C-H alkenylation/N-dealkylative carbonylation of tertiary anilines.
C-H/C-N activation: The first palladium/copper-catalyzed aerobic oxidative C-H alkenylation/N-dealkylative carbonylation of tertiary anilines has been developed. Various functional groups were… Expand
(E)-α,β-unsaturated amides from tertiary amines, olefins and CO via Pd/Cu-catalyzed aerobic oxidative N-dealkylation.
A novel Pd/Cu-catalyzed chemoselective aerobic oxidative N-dealkylation/carbonylation reaction has been developed. Tertiary amines are utilized as a "reservoir" of "active" secondary amines in this… Expand

When nanoparticles (NPs) are assembled from solution, a common assembly method of choice is either solution destabilization or solvent evaporation technique. The destabilization of the NP solution by… Expand
XANES/EPR Evidence of the Oxidation of Nickel(II) Quinolinylpropioamide and Its Application in Csp3 -H Functionalization.
An in situ generated oxidation species of nickel quinolinylpropioamide intermediate was produced. Characterization by X-ray absorption near edge structure (XANES) and EPR provides complementary… Expand
Palladium/Copper-Catalyzed Oxidative C—H Alkenylation/N-Dealkylative Carbonylation of Tertiary Anilines.
For the first time the aerobic title reaction is presented and furnishes the products in moderate to good yields tolerating a variety of functional groups.
(E)-α,β-Unsaturated Amides from Tertiary Amines, Olefins and CO via Pd/Cu-Catalyzed Aerobic Oxidative N-Dealkylation.
The Pd/Cu-catalyzed reaction of alkenes (I) with CO and tributylamine leads to a series of (E)-α,β-unsaturated amides (IV).
