Abstract

Abstract: Acylgermanes provide an outstanding photoinduced reactivity at very useful absorption wavelengths. This encouraged multidisciplinary research groups to utilize them as highly effective and non‐toxic photoinitiators particularly for medical applications. In this Minireview, we present the most recent breakthroughs to synthesize acylgermanes. We also outline mechanistic aspects of photoinduced reactions of several acylgermane derivatives based on fundamental spectroscopic insights. These studies may aid future developments for tailor‐made photoinitiators. Abstract : Acylgermanes have evolved as a promising class of visible light photoinitiators. This Minireview presents a summary of synthetic protocols and photochemical studies of acylgermanes. In addition, it outlines the superior properties of recently introduced tetraacylgermanes.
