The Aromaticity of Pericyclic Reaction Transition States Henry S. Rzepa
Presents an approach that combines two fundamental concepts in organic chemistry, chirality and aromaticity, into a simple rule for stating selection rules for pericyclic reactions in terms of achiral Hckel-aromatic and chiral Mbius-aromatic transition states.

"It Gets Me to the Product": How Students Propose Organic Mechanisms Gautam Bhattacharyya and George M. Bodner
Because practicing organic chemists use the arrow-pushing formalism in situations that are far removed from the simple contexts in which they are first presented, this study probed how students enrolled in a first-semester, graduate-level organic chemistry course approached the task of writing the mechanisms for two- to four-step reactions that lacked the typical cues that bring common mechanisms to mind. This article focuses on the students' solutions and discusses possible limitations of their strategies.

Pericyclic Reactions: FMO Approach-Abstract of Issue 9904M Albert W. M. Lee, C. T. So, C. L. Chan, and Y. K. Wu
Pericyclic Reactions: FMO Approach is a program for Macintosh computers in which the frontier molecular orbital approaches to electrocyclic and cycloaddition reactions are animated. The bonding or antibonding interactions of the frontier molecular orbital(s) determine whether the reactions are thermally or photochemically allowed or forbidden.

Programmed study aids for solving problems in advanced undergraduate organic chemistry Chenier, Philip J.; Jenson, Todd M.
The study aids presented here offer several advantages: a student gets just the amount of help that he or she needs; students learn how to do problems by solving part of a problem and are able to monitor how well they understand an idea.
