5.1.7 Product Subclass 7: Germylenes

Abstract

This chapter is a revised and updated version of the previous Science of Synthesis contribution describing methods for the synthesis of germylenes. As starting materials for the synthesis of germylenes, dihalogermanes and stable germanium(II) compounds {for example, GeCl₂•dioxane, GeI₂, and Ge[N(SiMe₃)₂]₂} have been used since the 1970s. In recent decades, digermynes and some new stable germanium(II) compounds such as chlorogermylenes, aminogermylenes, borylgermylenes, and hydrogermylene dimers have been synthesized, and these species have also been used as starting materials for the synthesis of germylenes.

Key words

germylenes - digermynes - germynes - digermanes - dihalogermanes - substitution - reduction - dissociation - insertion - addition
