Abstract
The 7-exo-configuration is assigned to all substituted tricarbonylcycloheptatrienechromiums previously prepared by the “normal” reaction of tricarbonyltropyliumchromium salts with anions. Several new examples are described, and displacement of methoxide from tricarbonyl-7-exo-methoxycycloheptatrienechromium is shown to be an advantageous alternative route to these products.Keywords
