Fig. 11.10 From top to bottom oxygen, selenium and germanium partial bond angle distributions (PBAD) in Ge02 and GeSe2 for an arbitrary N = 6 [118]. The colored curves correspond to PBADs having the lowest standard deviation(s) ag. The sharp peaks at 0 40° correspond to the hard-core repulsion. Labels defined in the bottom panel are used throughout the text...

Oxygen, sulfur or selenium insert in the germanium aUcali-metal bond (equation 78 and equation 79 ). 

Major drawbacks of tris(trimethylsilyl)silane relative to tri-n-butyltin hydride, however, are the cost of the reagent, the need to handle the reagent under argon and the propensity of the tris(trimethysilyl)silyl radical to add to multiple bonds. Many other silicon and germanium hydrides, as well as sulfur, selenium, and phosphorous radical transfer reagents have been investigated as tin hydride alternatives and while many have niche applications, none so far have the flexibihty or range of apphcations of tin hydrides. ...
