A series of novel triarylantimony (V) di(triphenylgermanyl)propionates with
the general formula ((Ph3GeCHRCHRCO2)-C-1-C-2)(2)SbAr3 (R-1 = H, Ph; R-2 =
H, CH3) were synthesized by the reaction of Ar3SbBr2 with triphenylgermany
lpropionic acid in the presence of triethylanaine. The in vitro antitumor a
ctivities of the title compounds against the five cancer lines are reported
.
