MESITYL BIS[(DIALKYLAMINO)]STIBANES AND ( DIARYLAMINO)]STIBANES

Some organo-bis(amino)stibanes were obtained from the reaction between mesityldichloro stibane and the corresponding lithium-amides. The uns tability of some of these compounds can be explained within Pearson's theory. These compounds are good precursors for the synthesis of mesit yldialkoxystibanes and mesityl-1,3-dioxa-4,6-di-t-butylbenzo-2-stibola ne. The reaction of mesityl bis(diethylamino)stibane with paranitroani line led to a new stiba-imine which has been characterized. This last compound appears very hygroscopic and gives the corresponding mesitylh ydroxyparanitroanilino-stibane also characterized in the reaction. All obtained compounds were analyzed by H-1 and C-13 NMR, IR and mass spe ctrometry.
