Organic Chemistry Division (III)

Report of Activities
August 1997 to July 1998

The current program of the Division of Organic Chemistry is organized within three commissions (III-1, III-2, III-3) and three subcommittees (Organic Synthesis, Bioorganic Chemistry, Nomenclature in 21st Century). In addition, the Division has the task of coordinating an Inter-Divisional project on Biomolecular Chemistry. The Division has, in line with IUPAC planning, strongly accentuated its bio-profile. As a consequence, it is expected that the name of the Division will undergo an alteration to reflect this significant change. During the report-period, the commissions and committees have actively contributed to the Divisional program. The status of the current activities, expressed as the results attained (in the past year) and the projected planning is summarized in the sequel.

In this on-line version of the Division Annual Report, a link on the Project Title will take you directly to the project description and progress.

International Conferences on Physical Organic Chemistry
Coordinators: Commission III.2
An important activity of the Commission is the organization of the biennial International Conference on Physical Organic Chemistry, of which the most recent was the 14th in Florianópolis, Brazil (August, 1998), with a Pre-Conference in Mexico City and a Post-Conference in Puerto Iguazú, Argentina. The next will be in July, 2000, in Göteborg, Sweden, and the 2002 meeting has been tentatively set for San Diego, USA.

Title: Reactions Pathways and Processes in Green Chemistry
Coordinator: P. Tundo
This project aims to examine new reaction pathways for the chemical industry as well as their impact on the environment. It is being carried out in cooperation with the Steering Group of the OECD Workshops on Sustainable Chemistry held in Washington July 3rd and to be held in Venice October 15-17. It is also in collaboration with Prof. Miyamoto, President of the IUPAC Division on Chemistry and the Environment, who will join the working party, which plans to produce a white book on chemistry and chemical technologies related to green (sustainable) chemistry, to focus on the two topics of technologies and organic synthesis.

Number: 320/22/98
Title: Evaluation of Methods for Obtaining Relevant Physicochemical Properties of Environmentally Important Organic Compounds
Coordinators: D. Lenoir and J. Altschuh
This is the second of two new projects dealing with important environmental issues. It will focus on various properties, such as vapor pressures and octanol/water partition coefficients, and the recommended methods for measuring them. A group of experts in the various measurements has been constituted. This project will be carried out in cooperation with IUPAC Commission VI.1 and with OECD, which has set rules for measuring these quantities.

Future Projects
Other issues of current interest to the Commission include "Acidity of Strong Acids", "Guidelines in Evaluating Reliability of Computational Methods", and "Biomolecular Mechanisms". The Commission reiterated its keen interest in participating in projects related to education. Former member Yoshito Takeuchi is now a member of the Education Committee, which is eager to collaborate with us in projects related to Organic Chemistry (not only Physical Organic Chemistry). Possible projects might concern recommendations for book writers, a survey of organic chemistry curricula in the various countries, and general recommendations about the material to be learned in order to facilitate international education.


Commission on Photochemistry (III.3)

Book Project
The proposed project to compile previous Commission Reports into an IUPAC Photochemistry Compendium has been dropped. Prof. Jacob Wirz has arranged for several of the Commission Reports to be posted on the European Photochemistry Association Web site at http://www.unibas.ch/epa/.

New Projects
Prof. Bolton is writing a Tutorial on Optical Terms and Units for Use in Photochemistry. This will probably be submitted to the News Letters of the three Photochemistry Societies for comments. A Project on Terms and Nomenclature in Ultraviolet Disinfection is planned in collaboration with the US Environmental Protection Agency. New projects will be further developed for presentation at the IUPAC Assembly in 1999.


SubCommittee on Organic Synthesis

A completely new committee was nominated in Jan. 1998. It is engaged in the following activities.

Number: 301/1/93
Title: Development of Guidelines for the transmission of Information on Organic Synthesis

International Conference on Organic Synthesis
The roster for the IUPAC Organic Synthesis (ICOS) meetings has been completed till 2002. ICOS-13 will be held in Warsaw, Poland (July 1-5, 2000). Invitation for ICOS-14 (2002) has been received from Christchurch, New Zealand.

Combinatorial Chemistry
In the context of Biomolecular Chemistry, activities in the area of Combinatorial Chemistry are being coordinated with Division VII.

Green Chemistry
Discussions on the coordination of the "Synthetic Dimension" of Green Chemistry are underway with the Physical Organic Chemistry group working on that project.

  • 1. Organization of small meetings on highly specialised areas, as satellite meetings to major conferences.
  • 2. Organization of symposia-in-print on (a) combinatorial synthesis, (b) development of "new transformations for industrial organic processes including "green" organic synthesis, (c) enantioselective synthesis and (e) synthetic enzymes.
  • 3. Establishment of South East Asian forum for exchange of information and experience in teaching methods, laboratory practices and other e.g. environmental issues. [Whereas this proposal has emerged from within the subcommittee, it will be coordinated with the other IUPAC activities on Education].


SubCommittee on Bioorganic Chemistry

Number: 302/2/96
