The addition of germatrane, HGe(OCH 2 CH 2 ) 3 N ( 1 ), to terminal acetylenes is catalyzed by [Cp*RhCl 2 ] 2 and yields styrylgermatranes The stereochemistry of the double bond can be controlled by the choice of solvent. In methylene chloride, ( E ) - β-styrylgermatranes are the major products, whereas in toluene ( Z ) - β-styrylgermatranes are the major products. The addition is also catalyzed by Pd(PPh 3 ) 4, giving ( E ) - β-styrylgermatranes regardless of solvent.
