Abstract
A copper-catalyzed pentafluoroethylation of aryl/alkenyl iodides is described using Et3SiCF2CF3 as a direct CF2CF3 source. An intriguing selective photocatalytic hydrodefluorination of pentafluoroethylarenes is also discovered.

Abstract
The Sb–E–P-bridged adducts of (F5C2)2SbCl and (3,5-(CF3)2C6H3)2SbCl with H(E)P(tBu)2 (E = O, S) show different bridging angles depending on substitution and bridging chalcogen atom. Starting from SbCl3, we also synthesised the volatile (F5C2)2SbH.

Abstract
A tetradentate host system with four C![[triple bond, length as m-dash]](https://www.rsc.org/images/entities/char_e002.gif)
C–Sb(C2F5)2 functions binds halide ions in a distorted square planar coordination. Experimental and calculated structures reveal a complex interplay of attractive pnictogen bonding and Coulomb repulsion.
