The bonding of an alkene to a transition metal complex is described in a model named for this chemist along with  Chatt and Duncanson.
This man deduced the structure of stipitatic acid, an aromaic compound containing a seven-membered ring, and he coined the term tropolone. In the field of computational chemistry, this man developed semi-empirical methods including modified NDDO and Austin method 1. Identifying transition states as either aromatic or anti-aromatic can be done using rules named for Zimmerman and this chemist. The bonding of an alkene to a transition metal complex is described in a model named for this chemist along with  Chatt and Duncanson. For 10 points, identify this man who shares his surname with a Scottish chemist who invented a flask that was the predecessor of the Thermos.
