An N,P‐heterocyclic germylene/B(C 6 F 5 ) 3 Lewis adduct 2 presenting multi‐reactive sites (P/B Lewis pair, germylene, Ge=P π‐bond) is reported. In contrast to classical frustrated Lewis pairs or divalent Group 14 element species, 2 is able to activate two small molecules simultaneously. Of particular interest, 2 reacts with silanes leading to the formation of original cationic germylenes 3 , and can be used as a metal‐free catalyst for selective CO 2 ‐hydrosilylation to H 2 C(OSiEt 3 ) 2 .
