Germanium organo compounds

The single-bond compounds between Si, Ge, and Sn and chalcogens (S, Se, Te) are reactive and used as synthetic intermediates in the synthesis of organic compounds, organochalcogen compounds, organo-silicon, -germanium and -tin compounds, and transition metal-chalcogen complexes and clusters. 

Equation (133)) and subsequently can be converted into a pentacoordinate 1,2-oxagermetanide (Scheme 23).173 Reaction of trichlorogermanes with mercaptoacetic acid or 2-mercaptoethanol also yields pentacoordinate organo-germanium compounds (Equations (134)174 and (135)).175...

Recent advances in acidity, complexing, basicity and H-bonding of organo germanium, tin and lead compounds ... 

The work was extended to the study of corresponding organo-germanium and -lead compounds and broadened to include a wider series of test fungi. 

The aim of this review is to focus on the hydrogen bonding, the acidity and basicity and complexing chemistry concerning the organo-element chemistry of germanium, tin and lead. This chapter is not exhaustive in scope, but contains the most recent work of the last five to six years, since another review in this series was published. This chapter emphasizes the synthesis, reactions and molecular structures of the class of compounds outlined above (less attention is paid to mechanism, spectroscopic properties and apph-cations which can be found in other specialized chapters). Especially, the single-crystal X-ray diffraction technique has elucidated many novel and unusual structures of molecules... 

Davies provides a comprehensive account of the state of organotin hydride chemistry up to the end of 1995 in his recent book , while Gielen and coworkers detail methods for the preparation of organo-germanium, tin and lead compounds in their 1995 contribution to this series the reader is referred to these works for chemistry which precedes that found in this chapter. The purpose of this account is to consolidate developments since the work of Davies and Gielen. Consequently, the preparation and synthetic uses of R3MH (M = Ge, Sn, Pb) from the beginning of 1996 until the end of 2000 are documented in this chapter. 

Organo triphenylstannyl tellurium compounds " and similar germanium and lead compounds reacted with copper(I) chloride at 20° in chloroform or diethyl ether to form copper(I) alkane- and arenetellurolates.
