Professor Dr. hab. Julian Chojnowski is an outstanding chemist who has significantly contributed to the development of many fields of organosilicon chemistry and organosilicon polymer chemistry. His fundamental research in the field of kinetic and thermodynamic aspects of polymerization processes and substitution at the silicon atom has led to understanding the mechanisms of ring-opening polymerization reactions of cyclic siloxanes, as well as the discovery of the importance of inter- and intramolecular catalysis in siloxane polymerization and polycondensation processes. His expertise in the field of siloxane polymer chemistry has resulted in cooperation with the leading silicone material manufacturers such as Dow Corning and General Electric Company. His collaboration with GE resulted in the discovery of several new reactions of hydride-functional silanes and siloxanes involving activation of Si–H bond by electron-deficient boranes. Recently, he expanded his research interest into silicon-based materials. He developed the synthesis of a new class of polymers, poly(oxymultisilylene)s, and new processes leading to the synthesis of highly cross-linked polyorganosiloxane beads, which can be subsequently converted into ceramic materials.
Professor Chojnowski was born on 17 June 1935 in Warsaw, Poland. He obtained his MSc degree in chemistry from Technical University of Lodz in 1957. He carried out his graduate studies at Technical University of Lodz under the supervision of Professor Stanisław Chrzczonowicz, where he obtained his PhD in 1963. In 1966, he spent two years as a postdoctoral fellow at the University of Wisconsin–Milwaukee, USA in the research group of Professor W.W. Brandt. Upon returning to Poland, he finished his habilitation in 1971. Shortly afterwards, he moved to the newly created Centre of Molecular and Macromolecular Studies of Polish Academy of Sciences, where he became the head of the Laboratory of Heteroorganic Polymers. In 1983, he obtained the academic title of Professor of Chemistry. He retired in 2005, but he continues research at the Centre of Molecular and Macromolecular Studies as a professor emeritus. Professor J. Chojnowski is the promoter of 15 doctoral dissertations. He published about 180 original papers, 16 review papers and chapters in books, as well as several Polish and US patents. He was also a co-editor of two books. In 2005, Professor Chojnowski was awarded the Jan Zawidzki medal for outstanding achievements in the field of physical chemistry by the Polish Chemical Society. He serves as a member of the Advisory Board of Journal of Inorganic and Organometallic Polymers and Materials, Silicon (Springer), and Main Group Chemistry.
Molecules is pleased to announce a Special Issue honoring Professor Julian Chojnowski on the occasion of his 85th birthday for his outstanding achievements in silicon chemistry. This Special Issue is dedicated to all aspects of organosilicon chemistry, including silicon-based polymer chemistry, mechanistic aspects of organosilicon chemistry, and catalysis and synthesis of silicon-based materials and ceramics.
We are pleased to invite you to submit a manuscript to this Special Issue; regular articles, communications, and reviews are all welcome.

Abstract: 3-Chloropropyltrimethoxysilane is a key intermediate for the manufacture of amino-, thio- and many other organofunctionalized silanes. It is manufactured via the Ru-catalyzed hydrosilylation of allyl chloride by trimethoxysilane. Over time, it was observed that allyl chloride obtained from various suppliers showed inconsistent rate and completeness of hydrosilylation. The problem was eventually traced to the need for peroxy compounds as promoters in the hydrosilylation. Already, it is known that hydrosilylations can be assisted or inhibited by peroxy compounds. In this case, allyl hydroperoxide and diallyl peroxide can be formed during the synthesis of allyl chloride. However, the concentrations retained in allyl chloride just prior to the hydrosilylation might be inadequate to promote the reaction due to thermal decomposition of the peroxy compounds during transport and storage. This paper will report the studies which led to the recognition of the critical role of peroxy compounds in the hydrosilylation process. The comparative performance of hydroperoxides, peroxides, peroxyesters in promoting the hydrosilylation will also be illustrated.
