Synthesis Explorer: A Chemical Reaction Tutorial System for Organic Synthesis Design and Mechanism Prediction Jonathan H. Chen and Pierre Baldi
Synthesis Explorer is an interactive tutorial system for organic chemistry that enables students to learn chemical reactions in ways previously unrealized. Pedagogical experiments in undergraduate classes at UC Irvine indicate that the system can improve average student examination performance by ~10%.

Oxidation of Aromatic Aldehydes Using Oxone Rajani Gandhari, Padma P. Maddukuri, and Thottumkara K. Vinod
Describes an eco-friendly procedure for the oxidation of aldehydes to carboxylic acids in water or a water-ethanol mixture using Oxone as the oxidant. The use of eco-friendly solvents, a non-toxic reagent, and the elimination of extraction solvents in the procedure demonstrate important green chemistry themes to students.

Ozonolysis Problems That Promote Student Reasoning Ray A. Gross Jr.
The structural features inherent in acyclic monoterpenes that follow the isoprene rule often lead to unique sets of ozonolysis products from which their structures, excluding stereochemistry, can be determined from molecular formulas only. This article shows how students may elucidate the structures of these compounds by analysis of the oxidative and reductive workup products.

Keynotes in Organic Chemistry (Andrew F. Parsons) Joel M. Karty
As a result of the trend towards modularization of chemistry courses, the text attempts to meet the need for smaller, highly focused and accessible organic chemistry textbooks, which complement the very detailed standard texts, to guide students through the key principles of the subject.

Organic Acids without a Carboxylic Acid Functional Group G. V. Perez and Alice L. Perez
This paper presents several organic molecules that have been labeled as acids but do not contain a carboxylic acid functional group. Various chemical principles such as pKa, tautomerization, aromaticity, conformation, resonance, and induction are explored.

Incorporating Organic Name Reactions and Minimizing Qualitative Analysis in an Unknown Identification Experiment Claire Castro and William Karney
The authors have developed a new type of unknown identification experiment for the introductory organic chemistry laboratory. The unknown sample the student is provided with is the product of an organic name reaction. The student is only informed of the starting material and conditions used in the compound's synthesis, and must then: (1) deduce the compound's structure, (2) determine the name reaction and corresponding mechanism that yields the compound, and (3) present his/her results to the class.

Organic Chemistry, Third Edition reviewed by Timothy D. Lash
The author continues to stress the use of reaction mechanisms, and this remains a strong point in the new edition. The heart and soul of modern organic chemistry revolves around these concepts, and this framework is essential for a textbook of this type.
