Abstrakt: 1.The reaction of the 3:1 molar ratio of the reagents HGeCl3 and triphenylamine at 20°C in benzene leads to the formation of a high yield of the iminium salt — cis-3,5-bis (trichlorogermyl)cyclohexylidenediphenyliminium trichlorogermanate, whereby the transisomer is initially formed in the course of the reaction; the trans-isomer of the iminium salt isomerizes spontaneously to the cis-isomer.2.The reaction of the 4:1, and greater, molar ratio of the reagents HGeCl3 and triphenylamine at 80°C leads to the formal hydrogenation of the initially formed iminium salt with the formation of 3,5-bis(trichlorogermyl)cyclohexyldiphenylammonium trichlorogermanate.
