The reactions of [2+3] cycloaddition of nitrileoxides to mono- and 1,2-disubstituted germylalkenes proceed regioselectively and resulted 5-Ge-substituted isoxazolines-2 from triethylvinyl- and triethylallylgermane and 4-Ge-isomers from β-triorganylgermylstyrene and ethyl triorganylgermylacrylates. In the latter case the reaction occurs stereospecifically: Z-germylalkenes give cis-, while E-germylalkenes
