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 ...
