Scheme 1. Synthesis of donor–acceptor-stabilised germaacid chloride 1. Notes: (a) in the alphanumerical numbering pattern, G denotes germylene, and D denotes germanium μ-oxo dimer, and (b) products with a Ge O → B(C6F5)3/Ge-OTMS → B(C6F5)3 moiety are given a linear/arbitrary numerical numbering pattern (starting from 1).
