It is hoped that the examples and the accompanying mechanistic discussions of electrochemical reactions of organosilicon compounds shown in this review will provide a guide to the potential utility of such reactions in organic synthesis and to the development of new electroorganic chemistry based on the unique properties of silicon. 

It should be very evident from the above survey that the field of organosilicon chemistry, and in particular the photochemistry of organosilicon compounds, is a very active area of research. The field is of increasing interest not only to chemists whose primary interest lies with the silicon aspect of the subject, but increasingly it is also of interest to organic chemists because of the synthetically novel and useful products of photolysis which can be obtained, and to photochemists where the field presents a wealth of different types of reaction, few of which have been studied mechanistically. It seems certain that there will continue to be great activity in the field of organosilicon chemistry in the near future. 

It is the purpose of this chapter to review selectively the advances in the synthetic applications of organosilicon compounds, excluding those organosilanes covered in other chapters. Since the publication of The Chemistry of Organic Silicon Compounds, two monographs1,2 and several reviews3-5 have been published, as have three conference proceedings6-8 and a symposium-in-print 9. 

Hopkinson was hired by York to teach theoretical organic chemistry (the Woodward-Hoffmann rules were then a hot topic) and to carry out experimental chemistry. Despite the limited computing capacity at York at the time, he managed to complete some work on the electrophilic addition to alkenes. He is probably best known, however, for his work on proton affinities, destabilized carbocations,234 organosilicon compounds, silyl anions and cations, and more recently, on the calculation of potential energy surfaces and thermodynamic properties. He has had a particularly fruitful collaboration with Diethard Bohme.235... 

This short text is intended to introduce the student of synthetic organic chemistry to the reactions of organoboron and organosilicon compounds which have been exploited by organic chemists, and to illustrate how these reactions have been applied to problems in organic synthesis. It is hoped that the chemistry described in this slim volume will encourage students to consult the more comprehensive reference texts and reviews available. These are listed in the bibliographies at the end of each section. 

The preceding volume on The chemistry of organic silicon compounds (Vol. 2) in The Chemistry of Functional Groups series (Z. Rappoport and Y. Apeloig, Eds.) appeared in 1998. It followed an earlier volume with the same title (S. Patai and Z. Rappoport, Eds.) published in 1989 (now referred to as Vol. 1) and an update volume The silicon-heteroatom bond in 1991. The appearance of the present volume only three years after the three parts of Vol. 2 reflects the continuing rapid growth of many sub-fields of organosilicon compounds and their chemistry. 

Silylenes Divalent, dicoordinate silicon compounds, are the silicon coimterparts to the carbenes well known in organic chemistry. Since silylenes are frequent intermediates in both thermal and photochemical reactions, their importance in organosilicon chemistry is great [1]. There is recent evidence that even the direct reaction of methyl chloride with silicon, the foundation stone of the worldwide silicone industry, may proceed through the formation of silylene intermediates [2].
