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
次级碳硅烷之间的反应1 - 3和1- propylbiguanide / 1-苯基双胍,H 6 bigR经由的SiH / NH继续dehydrocoupling和得到1,4-双(甲硅烷基)-5-丙基/与通式phenylbiguanides(R 1 - [R 2 2 SiCH 2 CH 2 SiMeH)2 ·H 4 bigR,[R 1= Ph,R 2= Me,R =n Pr(4),R = Ph(5);R 1= Me,R 2= Ph,R =n Pr(6),R 1= R 2= Et,R = Ph(7)]。这些化合物代表了由[Si-NCNCN]螯合环组成的五配位硅衍生物的新家族,并通过元素分析,FAB质量,IR和多核(1 H,13 C和29 Si)NMR光谱研究进行了表征。
