Continuous Microwave-Assisted Synthesis of Silver Nanoclusters Confined in Mesoporous SBA-15: Application in Alkyne Cyclizations featured on the cover of CHEMISTRY OF MATERIALS
About the cover: Metal nanoclusters are becoming exciting candidates as highly efficient catalysts for fine chemical production in view of their extraordinary surface to volume ratio and the high concentration of uncoordinated atoms that contributes to enhanced catalytic activity. However, cluster recovery and recyclability are the main obstacles to facilitate their use in heterogeneous reactions. The cover art shows Ag nanoclusters produced by an innovative microwave-based approach. The nanoclusters, depicted as an allegory of catalytic scissors, were used for the activation of alkynes showing excellent activity for the formation of a wide variety of molecular bonds (C−O, C−N, and C−C).
