چکیده
The Front Cover illustrates how multicomponent reactions offer dreamlike opportunities for the conversion of biobased scaffold 5-Hydroxymethylfurfural (HMF) towards complex structures, and ammonium acetate acts as a mild catalyst such [4+2+1] cycloadditions acid-sensitive substrates. This “enchanted” cover, sponsored by INSA Lyon, was designed Lyon artist Adrien Demingeon (https://www.instagram.com/Taken0w). More information can be found in Research Article Y. Queneau, F. Popowycz et al.

Ni(NHC)]-Catalyzed Cycloaddition of Diynes and Tropone: Apparent Enone Cycloaddition Involving an 8π Insertion
A Ni/N-heterocyclic carbene catalyst couples diynes to the C(α)-C(β) double bond of tropone, a type of reaction that is unprecedented for metal-catalyzed cycloadditions with aromatic tropone. Many different diynes were efficiently coupled to afford [5-6-7] fused tricyclic products, while [5-7-6] fused tricyclic compounds were obtained as minor byproducts in a few cases. The reaction has broad s...
متن کاملAdamantane-1-ammonium acetate
In the title compound, C(10)H(18)N(+)·C(2)H(3)O(2) (-), the ammonium H atoms of the cation are linked to three acetate anions via N-H⋯O hydrogen bonds, forming a chain structure extending along the b axis.
متن کاملCu-catalyzed azide-alkyne cycloaddition.
The Huisgen 1,3-dipolar cycloaddition reaction of organic azides and alkynes has gained considerable attention in recent years due to the introduction in 2001 of Cu(1) catalysis by Tornøe and Meldal, leading to a major improvement in both rate and regioselectivity of the reaction, as realized independently by the Meldal and the Sharpless laboratories. The great success of the Cu(1) catalyzed re...

Addition of ammonium acetate fo llowed by commerc ial zinc dust to the solution of azo compounds in methanol appcars to o ffer a general and convenient mea ns for reducing bot h sym metri ca l and unsymmetrical azo compounds to the corresponding amine/s at ambient temperature. Many other reducible and hydrogenolysable groups like -OCH1. -OH. -COOH, -CH1• -COCH) and halogens are to lerated. The ...

The integrated Rule Oriented Data Management System (iRODS) is a policy-driven data management system that is starting to be used by projects with large data volume requirements that require a highly available system. In this paper we describe an approach to provide a Highly Availability load-balanced iRODS System (HAIRS). We also describe the advantages and disadvantages of the approach and fu...
