Si(CH2)3SiMe2Cl}4 “G[0]-[Cl]4” (12) and itsfirst generation analogue Si[(CH2)3SiMe(CH2)3SiMe2Cl}2]4 “G[1]-[Cl]8” (15) were reacted with, respectively, four and eight molar equivalents of the lithium alkoxy derivative of 9 giving the two functionalized dendrimers G[0]-[OCH2CH2Otriphos]4 (13) and G[1]-[OCH2CH2Otriphos]8 (16). These were metallated with four and eight molar equivalents of [Rh(COD)2][BF4] in CH2Cl2
