The scope and performance of oxidativecouplingreaction using MoCl5 can be significantly improved by employing Lewis-acidic additives such as TiCl4, SnCl4, or SiCl4. Since the by-product, HCl, plays a particular function as an inhibitor for MoCl5 by forming chloro complexes, exploiting typical chloride scavengers, like silver salts or molecular sieves, is also successful. A variety of differently
