3-spiroindolizines containing an isoindole ring through intra-molecular arylation of spiro-N-acyliminium species

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, ...
