✦ Synopsis

Abstract

The objective of this study was to synthesize a new bifunctional photoinitiator by the reaction between 1‐hydroxy‐cyclohexyl‐phenyl‐ketone and 3‐isocyanato propyl trimethoxysilane (ICPTMS) and examine its capability in the photoinitiation process comparing it with the unmodified photoinitiator. This new photoinitiator also acts as a coupling agent for inorganic and organic phases. Therefore, its effect on the physical and mechanical properties of UV‐curable transparent organic‐inorganic hybrid coatings was investigated. The presence of the new bifunctional photoinitiator and TEOS, increased the abrasion resistance and also improved the hardness of the polymeric films.

A novel hybrid photoinitiator, p-benzoyldiphenyliodonium hexafluorophosphate (PhCOPhI+PhPF&), was synthesized, characterized, and studied. It absorbs UV light not only below 300 nm, but above 300 nm as well. When exposed to UV light, it undergoes an asymmetrical photocleavage to produce cation-radic

## Abstract A novel approach for the synthesis of the important indole ring is described. Indoles are obtained from __o__‐bromoanilines and alkenyl halides in a Pd‐catalyzed cascade process that involves an alkenyl amination followed by an intramolecular Heck reaction. The overall process represent
