This study explores the aromaticity of doubly [5]helicene-bridged (1,4)cyclophane and triply [5]helicene-bridged (1,3,5)cyclophane via calculations of the magnetic response and of electronic aromaticity indices. The primary objective is to assess the π-electron delocalization to determine whether they sustain global ring currents associated with π aromaticity. The molecules show local ring ...The cover illustration shows a representative example of a metalation using frustrated Lewis pairs.

Pd-catalyzed cross-coupling has emerged over the past 35 years as one of the most versatile methods for C-C single bond formation. In addition to the use of Pd as a catalyst, the use of the stoichiometric amounts of regio- and stereo-specifying metals, especially Zn, Zr, and Al (Negishi) and B (Suzuki), also serve as kinetic and thermodynamic promoters. In particular, Pd-catalyzed ...
