Abstract: In this paper trichlorogermyl propionyl chlorides Ⅱ_a-c were prepared by the reaction of trichlorogermyl propionic acid Ⅰ_a-c with sulfenyl dichloride in 86%～9.1% yields.The compounds Ⅱ_a-c reacted with thiazolidine-2-thione or 2-mercaptobcnzothiazolc to form the N-(trichlorogermyl) substituted propionyl-thiazolidine-2-thione Ⅲ_u-c and N-(trichlorogermyl) substituted propionyl benzothiazoline-2-thione IV_a-c in 62.9%～97.7% yields.The β-substituted propionyl thiazolidine-2-thionyl germanium sesquioxide Va-cand β-substituted propionyl benzothiazoline-2-thionyl germanium sesquioxide VIa-c were obtained by hydrolysis of compounds Ⅲ_a-c and Ⅲ_a-c in 44.0%～83.8% yields.The compounds Ⅱ_b-c, Ⅲ_a-c, Ⅳ_a-c, Ⅴ_a-c and VI_a-c are new compounds.
