e Eighth International Symposium on Organosilicon Chemistry was held onthe campus of Washington University, St. Louis, MO1June-7 to 12, 1987. Over 400participants from 20 countries attended the conference, which was held underthe sponsorship of the International Union of Pure and Applied Chemistry. Agoal of the symposium organizers was broad coverage of all areas of cilrrentinterest in the whole field of silicon chemistry. This was achieved in thepresentations of three plenary and 49 invited lecturers, supplemented by 110poster presentations. Of the 52 principal speakeis, 49 contributed writtenversions of their talks as chapters in the symposium volume (565,pp) entitledSilicon Chemistry, published by Ellis Horwood, Ltd., Chichester' in February1988, under the editorship of the symposium cochairprsens -

After the Monday morning session in which the three plenary lecturers L.A.Paquette, H. Sakurai, and D.R. Weyenberg spoke, there were three parallelsessions of oral presentations. %The major subdivisions in which the oral andposter presentations were organized were:

g.Silicon-Assisted Organic Synthesis""-4LOrganic Chemistry of Silicon' _-$"ilicon in Living Systems;-C.Physical Chemistry, Theoretical Studies, Spectroscopy,-§ Silicon Reactive Intermediates)'-9-Silicon-Silicon Chemistry''R Silicon-Oxygen Polymers and Materials-

Inorganic Chemistry of Silicon) o ,c

Silicon in Solid State Technology,.( A.

The names of the invited lecturers and the titles of the sessions they ledare given below. Among the innovations of the conference was the incorporationof the poster presentations in the sessions of oral presentations This wasdone by offering poster presenters the opportunity to give a five-minute oralsummary of their work with a maximum of two slides. These poster summarieswere included in the appropriate sessions for the subject matter presentedwhenever possible.

Another novel feature of the symposium was the competitive award of 25Symposium Fellowships of $250 each to outstanding young scientists inrecognition of their research accomplishments and their promise for futureachievements. The Organizing Committee was happy to welcome this nextgeneration of leaders in the field of silicon chemistry and wish the number ofawards could have been greater. The 25 Symposium Fellows represented 15countries, and were selected from a group of ca. 75 applicants. The Fellowswere all young faculty or research institute members in the first few years oftheir careers, or postdoctorals about to begin their independent researchcareers. A special reception brought together these young stars of the futurewith the dozen winners of the Frederic Stanley Kipping Award in Organosilicon rChemistry who participated in the symposium

Silicon chemistry is unusual in that both the basic science and its -

technological applications are developing with dramatic rapidity. Thusmeetings like this one are not social occasions but vital communication links.A feeling of excitement about the field, both its present and future, permeatedthe meeting, and it seemed to be quite successful.
