Leveraging the impact of supply chain integration through information technology

Purpose - Companies increasingly exchange information to work more closely with supply chain partners. Although information exchange is a critical element for up-and downstream partnerships, the purpose of this paper is to indicate that it is not a guarantee for improved performance and should be combined with other integration tactics to fully capture its benefits. Design/methodology/approach - Using a global sample in the industrial sector, a moderated mediation framework for both upstream and downstream integration, which links integration tactics to operational performance, was empirically tested. Findings - This research shows that operational integration is indispensable to capture the benefits of information exchange. In addition, it points out that the impact of the use of information technology (IT) is stronger for upstream integration. Practical implications - While the data show that the use of IT significantly improves the delivery performance in the supply chain, it also signals to managers how and when to invest in supply chain integration tactics. Originality/value - This paper contributes to a better understanding of the supply chain integrationperformance link, by clarifying some of the inconsistencies in previous literature and by simultaneously analyzing upstream and downstream implications.

Inserting CO2 into Terminal Alkynes via Bis-(NHC)-Metal Complexes

The direct interaction between CO2 and terminal alkynes in the presence of bis-(NHC)-metal catalysts at ambient conditions was studied. Two Cu and Ag-based bis-N-heterocyclic carbene Transition Metal catalysts were synthesized. The (NHC)(2)-Ag complex showed a better catalytic performance towards the carboxylation of terminal alkynes in comparison with the copper analogue even for the conversion of acetylene gas. The optimized conditions for the carboxylation are: the use of Cs2CO3 as additive, one atmosphere CO2 and room temperature using 1% mol catalyst. Mechanistic insight into the reaction mechanism is obtained by means of state-of-the-art first principles calculations.
