Appropriation and land use in Blandy-les-Tours (Seine-et-Marne), from the 16th to the 19th century
Recent work, part of a process of opening up to multidisciplinarity, has underlined that the organisation of rural societies can no longer be understood without taking into account their relationship to space. These developments are now leading to work on the spatial dimension of data extracted from ...

Based on N-acyliminium species, efficient approaches to spirocyclic systems connected by two different carbon centers to the isoindole ring have been developed. The imide reduction and the tandem oxidative cleavage of olefin/formyl-amide equilibration were at first selected as the key steps for ...
Reactivity of CuI and CuBr toward Dialkyl Sulfides RSR: From Discrete Molecular Cu4I4S4 and Cu8I8S6 Clusters to Luminescent Copper(I) Coordination Polymers
The CuX salts (X = I, Br) react with SR2 to form molecular clusters of the types [(R2S)4(Cu4I4)] and [(R2S)6(Cu8I8)] or to give 1D polymers and 2D metal−organic frameworks. The cluster nuclearity and connectivity as well as the dimensionality of these compounds depend on the steric demand of SR2, ...
