The transition-metal catalysed [2+2+2] cycloaddition reaction is a highly efficient synthetic tool that allows six-membered polysubstituted carbo- and heterocyclic derivatives to be obtained in an atom economy process. ...
The transformation of C-H bonds into C-O/N bonds is a process of interest in organic synthesis, but controlling the reactivity and selectivity among the multiple C-H bonds existing in most molecules is a challenging task. ...
The present study focuses on the characterization of solid-liquid extraction techniques for the separation and preconcentration of rare-earth elements and precious metals. We developed an impregnated resin with di ...
