Fourteen new triphenylgermanium derivatives of alkynyl or alkenyl phosphonic acid were synthesized by the reaction of corresponding triphenylgermanium chloride with alkynyl or alkenyl phosphates. All compounds were characterized by elemental analysis, IR, 1H NMR and MS. The results showed that bis(triphenylgermanium) alkynyl or alkenyl phosphonates are both four- and five-coordinated germanium and triphenylgermanium alkynyl or alkenyl phosphonates are five-coordinated germanium.
Thirteen title compounds Ph 3GeS 2CNR 2(1—13) were synthesized by the reaction of \{corre\|\}sponding triphenylgermanium chloride with dithiocarbamates. Their structures were confirmed by elemen\|tal analysis, IR, 1H NMR, UV and MS. Some of these compounds showed antitumor activities in vitro.
