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 (R^ISiCt^Ct^SiMeH^HztbigR, [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.
