Cover: Difluorotriorganylphosphoranes for the Synthesis of Fluorophosphonium and Bismuthonium Salts

Cover
The cover picture shows a note system starting with a stacked group of three semibreves. These notes symbolize the three phosphorus(V) species discussed in this paper, namely trifluorophosphates, [R3PF3]-, difluorophosphoranes, R3PF2, and fluorophosphoranes, [R3PF]+. As in the periodic table, the heavy homologue bismuth is located on a lower note. Details are discussed in the article by B. Hoge et al..
