Back Cover: Phosphanyl Cyanophosphide Salts: Versatile PCN Building Blocks (Angew. Chem. Int. Ed. 33/2019)
First published: 10 July 2019
Graphical Abstract
The synthesis of derivatives of cyanophosphide [PCN]2− is described by H. Grützmacher, J. E. Borger et al. in their Communication on page 11429 ff. The characters Au, B, and NHC indicate the substituents onto which PCN can be transferred. The two Chinese characters translate into “Duan Wu”, which refers to the Dragon Boat Festival taking place on the fifth day of the fifth month of the Chinese calendar. It is believed that the fifth month may be one of bad luck so the racing dragon boats are meant to protect the new building block.
