OMCOS is a single-session international scientific conference that brings together industrial and academic chemists from around the world to discuss recent advances in metal-mediated and catalyzed reactions. The conference focuses on catalyst/ligand design, mechanistic insights, new processes/automation, novel preparations and uses for organometallic reagents, as well as the metals in the synthesis of pharmaceuticals, fine chemicals, agrochemicals and materials.

Catalytic processes involving organometallics are often unsurpassed in elegance and efficiency and they contribute decisively to the goal of economically and ecologically sound processes of production. The exciting and powerful field of asymmetric catalysis receives particular attention in the OMCOS programs.

The conference is held every two years, and its venue rotates among the Americas, Europe, and Asia.

• OMCOS is directed by an International Advisory Board (IAB) consisting of former OMCOS conference Chairs. The IAB can elect additional members from countries with strong OMCOS activity and participation (and to build a diverse and representative Board).
• Membership in the IAB is limited to ten OMCOS events following the Chair's conference.
• The IAB discusses candidatures and decides four years ahead of the event on a venue and the Chair(s) of the that symposium.
• The IAB elects from the ranks of past OMCOS conference Chairs a Secretary for two successive future OMCOS events. The Secretary provides outlines and date markers for the preparation of the conference and stays in close contact with the OMCOS Chair(s) on organizational matters. The Secretary solicits bids for future OMCOS conferences.
• Chairs retired from the IAB are listed in the section as Honorary Board

OMCOS Secretary for the period of 2025-2027:

Chulbom Lee, Seoul National University, Republic of Korea, e-mail: chulbom@snu.ac.kr

Future-OMCOS conferences:

• OMCOS 22 (2025): Sept 1-5, 2025, Kyoto, Japan (Co-chairs: Michinori Suginome, Hideki Yorimitsu)
• OMCOS 23 (2027): Lausanne, Switzerland (Chair: Nicolai Cramer)
• OMCOS 24 (2029): Bids are invited for the 2029 conference. Please contact the Secretary.

Procedure:

• A brief (ca 3 pages) summary (with/without pictures) of an application addressing some of the points listed below should be sent to the secretary by May 1, 2025. This will be forwarded to the members of the Advisory Board in preparation of its meeting at OMCOS 22.
• At OMCOS 22 in Kyoto, applicants present a max 8 min powerpoint presentation of their candidature (venue, potential for participation, housing, etc.). This then will be discussed and a decision is taken. Presentation by the applicant(s) chair is best although a member of the future committee can substitute.

Conditions for Chair(s):

• The OMCOS Chair(s) carries the full burden of organizational tasks and financial risks. The Chair(s) also takes charge of setting up local and national conference boards, and an international award committee for the OMCOS Award. The Chair(s) raises funds for this award.
• The OMCOS Chair(s) should be prominent scientist(s) in the field with a high international scientific reputation. He (she, they) should engage the local/regional/national community in both academia and industry to support the conference.
• Facilities are required to host an important meeting of 500-1200 participants in a single session conference. A split into parallel sessions is to be avoided except for contributed oral communications, if desired.
• Facilities are required to hold extensive poster session(s) (which can be complemented by an exhibition). Posters should be widely spaced and there should be ample time allowed for discussion. Poster prizes should be a feature and, if the sessions are organized in the evening, drinks and snacks should be provided.
• The Chair(s) puts together a scientific program that includes lectures in key areas of the field, and that includes prominent experienced practitioners as well as promising young researchers. A balance of geographical provenance of speakers is another important aspect. Plenary speakers should not have previously lectured in this capacity at one of the four former OMCOS meetings. The program should attract scientists from both academia and industry.
• Registration fees should not exceed those of similar large international meetings. Strongly reduced fees (max 50%) should be offered to young scientists (e.g. students and postdocs <33 years of age). Rates should include welcome receptions, coffee-breaks, lunches, and poster parties.
• OMCOS has a historic reputation not only for the excellence of the science being presented and discussed but also for the high level of hospitality offered to lecturers and participants. Conditions must be particularly attractive to young participants (accommodation, poster party, and poster prizes.
• Decisions on the program (speaker selection), fundraising, organization, and all other matters concerning an OMCOS conference including finances rest entirely in the hands of the Chair(s) and his/her committee(s) and are his/her sole responsibilities. Input from the Board members is encouraged to help identify young researchers in their country.
• After the conference, the OMCOS chair(s) sends a short illustrated report to the secretary (pdf file).
• Under the heading “OMCOS History and Organization” the conference website includes the list of former events (with reports), the members of the IAB and the Honorary Board, and information on OMCOS organization, future events, and conditions for Chair(s).
