Notes:
Reaction of the ferriodisilanes C5R5(OC)2Fe-Si2H5 [R = H (1a), Me (1b)] with dimethyldioxirane leads to selective insertion of oxygen into the α-Si-H bonds to yield the ferriodihydroxydisilanes C5R5(OC)2Fe-Si(OH)2-SiH3[R = H (2a), Me (2b)]. Another access to yield 2a is opened by hydrolysis of the dichloro(ferrio)disilane Cp(OC)2Fe-SiCl2-SiH3 (3a). Treatment of the pentachloro(metallo)disilanes C5H5(OC)2Fe-Si2Cl5 (4a) and C5Me5(OC)2Ru-Si2Cl5 (4b) with water results in regiospecific hydroxylation of the β-silicon atom to generate metallodisilanetriols C5R5(OC)2M-SiCl2-Si(OH)3 [M = Fe, R = H (5a); M = Ru, R = Me (5b)]. Controlled condensation of 5b with Me2Si(H)Cl leads to the novel rutheniosiloxane C5Me5(OC)2Ru-SiCl2-Si(OSiMe2H)3 (6).
