Novel germanium(ii) binaphthoxide complexes: synthesis and crystal structure of (R,R)-[Ge{OC20H10(OSiMe3)-2′-(SiMe3)2-3,3′}2] and (R)-[Ge{O2C20H10(SiMe2Ph)2-3,3′}{NH3}]; catalytic function of Ge[N(SiMe3)2]2 for the mono-silylation of 3,3′-disubstituted-1,1′-bi-2,2′-naphthols
Abstract
The germanium(II) bisamide Ge[N(SiMe3)2]2 reacts with the substituted binaphthols (R)-[(HO)2C20H10(R)2-3,3′] (R = SiMe3, SiMe2Ph, SiMePh2, or SiPh3) to yield two novel germanium(II) binaphthoxide complexes; Ge[N(SiMe3)2]2 also catalytically silylates one of the hydroxyl groups of (R)-[(HO)2C20H10(SiMe3)2-3,3′] to yield (R)-HOC20H10-(OSiMe3)-2′-(SiMe3)2-3,3′.
