Bis germyl

Hexamethyldigermane reacts with terminal alkynes at 120 °C in the presence of Pt(acac)2 to give (Z)-l,2-bis(germyl) ethenes in moderate yield (Equation (55)).137... 

Treatment of the chloride 142a with 5% solution of KOH in methanol followed by neutralization with citric acid gave germanol MeC(0)N(Me)CH2GeMe20H. In the case of bis-germyl derivative 142d the product of heterocyclization 151 was obtained (equation 38)485. 

Reaction at a higher temperature leads to the formation of bis(germyl)metal carbonyls that exist as a mixture of two isomers (equation 17)87,88. The latter complexes were also synthesized directly by an exchange reaction between Na2Fe(CO)4 and R3GeCl19. 

The reaction of the bis(germyl)carbodiimide 22 with SiHsBr affords the corresponding bis(silyl)carbodiimide 23. ...

While a very wide variety of 2-metalloidal-1,3-dithianes can be prepared, even including bis(silyl), bis(germyl), or mixed metalloidal compounds,... 

Some preliminary photochemical studies have been made. Photolysis of the bis(germyl) ketone under nitrogen in benzene or methanol led to rapid decolorization of the orange solution and high yields of hexaphenyldigermane, presumably through a Norrish Type I cleavage. When photolyzed... 

Photolysis of the bis(germyl) ketone in benzene in the presence of air afforded in addition to hexaphenyldigermane, the previously known triphenylgermyl triphenylgermanecarboxylate (90) the latter compound and triphenylchlorogermane were formed in carbon tetrachloride.
