A benzene 1 ml solution of 1,2-diphenyltetrameth-
yldigermane 0.5 mmol , trans-cinnamyl chloride 1
mmol and Pd2 dba . CHCl3 0.005 mmol was stirred
at room temperature. The reaction was traced with a gas
chromatograph. After 1 h, a 94% of the digermane was
consumed and trans-cinnamyldiethylphenylgermane and
its cis-isomer were formed in 96% and 3% yields based
on the digermane consumed, respectively. However, H
NMR analysis of a mixture of the products collected
with GLC column; silicone KF-96, 10% on celite 545
AW disclosed that the products consisted of trans-iso-
mer 88% , cis-isomer 11% and 1-phenylprop-2-
enyl dimethylphenylgermane 1% . A similar product
distribution was also observed in GLC analysis of the
