Advanced Synthesis &Catalysis, EarlyView.A Ti(III) complex synthesized mechanochemically catalyzes the cycloaddition of CO2 (1 bar) with terminal, internal, and trisubstituted epoxides. Mechanistic studies by density functional theory calculations reveal that the superior activity of Ti(III) compared to Ti(IV) arises from its lower oxophilicity, facilitating CO2 insertion into Ti–O bonds, as ...

SECTORAL EFFECTS OF A WORLD OIL PRICE SHOCK: ECONOMYWIDE LINKAGES TO THE AGRICULTURAL SECTOR [PDF]
The effects of a world oil price shock on U.S. agriculture are analyzed in an economywide environment. We use an input-output model to analyze the direct and indirect cost linkages between energy and other sectors of the economy.

Advanced Synthesis &Catalysis, EarlyView.A series of amidines are prepared via PIII/PVO redox catalyzed in situ formation of imidoyl chlorides from amides. The desired products are obtained in good to excellent yields. Moreover, the protocol is applied to the synthesis of Erlotinib. Amidines are a ubiquitous class of bioactive compounds found in a wide variety of natural products; thus ...

Production and Trade in Services by U.S. Multinational Firms [PDF]
Direct investment in foreign countries by U.S. goods industries represents a response to differences in labor costs to a much greater extent than the more rapidly growing investment by service industries.

Advanced Synthesis &Catalysis, EarlyView.A solvent‐free mechanochemical reduction of nitro compounds using hydrogen gas is presented. In addition to enabling the synthesis of a variety of functionalized aniline derivatives, the method has been scaled up to gram quantities, evaluated for trace metal impurities, and applied to the synthesis of pharmaceutical compounds and their precursors.

Redrawing the Mannich‐Type Reaction through Carbonyl Umpolung Reactivity
Advanced Synthesis &Catalysis, EarlyView.GA: Herein, a conceptually novel one‐pot multicomponent strategy is reported for the streamlined construction of five‐membered imidazolidines from 1,2‐diaza‐1,3‐dienes (onefold), amines (twofold), and formaldehyde (twofold). This redesigned Mannich‐type reaction that exploits a carbene‐like activity of 1,2‐diaza‐1,3‐dienes (realized by “umpolung ...
