Welcome to the OMCOS web site


The OMCOS series of biennial symposia started in 1981. Its venue alternates between North America, Europe and East Asia. It is a single session type scientific conference that brings together industrial and academic chemists from around the world (often > 1000) to consider the most recent developments in new metal-mediated and -catalyzed reactions, mechanistic insights and new applications, novel preparations and uses for organometallic reagents, as well as ingenious and improved methods for the synthesis of pharmaceuticals, agrochemicals and materials using metals.

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 young, exciting, and powerful field of asymmetric catalysis receives particular attention in the OMCOS programs.

Next OMCOS Symposium:

OMCOS 21 will take place in Vancouver BC, Date TBD.

OMCOS Organization

  • OMCOS is directed by an Advisory Board (AB) consisting of former OMCOS conference Chairs.

  • The AB discusses candidatures and decides four years ahead of the event on a venue and the Chair(s) of the symposium.

  • The AB elects from the ranks of past OMCOS conference Chairs a Secretary General (SG) for two successive future OMCOS events. The SG 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 SG solicits bids for future OMCOS conferences.

OMCOS Secretary for the period of 2017-2021:

Prof. Mark Lautens, University of Toronto, Canada, e-mail: mark.lautens@utoronto.ca

Future OMCOS conferences


Vancouver, Canada (chairs: Jennifer Love and Laurel Schafer), Summer 2021.



  • The OMCOS Chair should be a prominent scientist in the field with a high international scientific reputation. He (she, they) should be able to count on a strong scientific local/regional/national environment in the field in both academia and industry.

  • Facilities are required to hold an important meeting of 1000 (or more) scientists in a single session conference. A split into parallel sessions is to be avoided except for contributed oral communications, if desired.

  • Facilities to hold extensive poster session(s) (can be complemented by an exhibition) Posters should be appropriately widely spaced and there should be ample time for discussion. Poster prizes should be a feature and, if the sessions are organized in the evening, drinks and snacks should be provided.

  • The organizer(s) puts together a scientific program that includes lectures in key areas of the field, and that includes prominent experienced practitioners in the field as well as young promising 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 to the meeting.

  • Registration fees should not exceed those of similar large international meetings. Strongly reduced fees (<50%) should be offered to young scientists (e.g. students and postdocs <33 years of age). Rates must include receptions, coffee-breaks, lunches, poster parties, etc.

  • OMCOS has an excellent 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, poster prizes, etc).

  • For conferences of the OMCOS series, the organizer carries the full burden of organizational tasks and financial risks. The chair(s) also take charge of setting up a local and national conference board, and an international nomination committee for the OMCOS award (recipient < 40 years of age). The chair(s) raise funds for the award.


The OMCOS Award was established to recognize a scientist under the age of 40, who has made significant contributions to the field of organometallic chemistry and organic synthesis. This award, sponsored in recent years by the Yen Chuang Foundation, is presented every two years on the occasion of the OMCOS conference.
