Abstract: The reactions between secondary carbosilanes 1–3 and 1-propylbiguanide/1-phenylbiguanide, H6bigR proceed via SiH/NH dehydrocoupling and afford 1,4-bis(silyl)-5-propyl/phenylbiguanides with the general formula (R1R22SiCH2CH2SiMeH)2·H4bigR, [R1=Ph, R2=Me, R=nPr (4), R=Ph (5); R1=Me, R2=Ph, R=nPr (6), R1=R2=Et, R=Ph (7)]. These compounds represent a new family of pentacoordinate silicon derivatives comprising of [Si-N-C-N-C-N] chelate ring and have been characterized by elemental analysis, FAB mass, IR and multinuclear (1H, 13C and 29Si) NMR spectral studies.
