ResumoAbstract Both β-(E)- and β-(Z)-styryltrimethylgermanes easily reacted with arenediazonium tetrafluoroborates under palladium catalysis to give aryldegermylated products, (E)-PhCH=CHAr and Ph(Ar)C=CH2. On the other hand, the aryldegermylation of α-styrylgermane gave (E)-stilbene derivatives with high stereo- and regioselectivities.
