Digermyl ether

Digermyl sulfide has been used as an intermediate in the preparation of germanethiol (mercaptogermane),2 4 and digermyl ether.5 In view of the utility of disilyl sulfide as an intermediate,6 it seems likely that the germyl analog will be exploited further. 

Investigations in the field of germylium and stannylium ions met with little success in the 1990s. Lambert et al. reported the synthesis of the protonated digermyl and distannyl ethers (R3E)20H TPFPB (R = Me, Et E = Ge, Sn), which possess significant amounts of germylium and stannylium ions character. ... 

Digermyl sulfide (digermathiane) has been prepared by the reaction of iodoger-mane with mercury(II) sulfide and, more recently, from bromogermane and dilithium sulfide in dimethyl ether. (Methylthio)germane has been prepared by...
