Abstract
The metallodisilanes C5R5(OC)2Fe-Si2Cl5 (2a, b) and C5R5(OC)2Fe-Si2H5 (3a, b) (R = H, Me) used for the synthesis of metallodisilanols have been structurally characterized. Hydroxylation of Cp(OC)2Fe-Si2Me4Cl (4) has been realized with water in the presence of Et3N to yield the corresponding ferriodisilanol Cp(OC)2Fe-Si2Me4OH (5). Formation of the metallodichlorotrihydroxydisilanes C5R5(OC)2M-SiCl2-Si(OH)3 [R = H, M = Fe (7a); R = Me, M = Ru (7b)] is achieved by regioselective hydrolysis of the metallopentachlorodisilanes 2a and C5Me5(OC)2Ru-Si2Cl5 (2c). In an analogous manner [Cp(OC)2Fe-SiC12]2 (11) is converted to [Cp(OC)2Fe-Si(OH)2]2 (12). Controlled base-assisted condensation of 5, 7b and 12 leads to the formation of the novel metallodisilanesiloxanes CP(OC)2Fe-Si2Me4OSiMe2H (6), Cp*(OC)2RU-SiCl2Si(OSiMe2H)3 (8) and [Cp(OC)2Fe-Si(OSiMe2H)2]2 (13). Specific introduction of hydroxyl groups at the α-silicon of metallodisilanes is realized by conversion of the ferriodisilanes C5R5(OC)2Fe-Si2H5 (3a, b) into the ferriodichlorodisilanes C5R5(OC)2Fe-SiCl2SiH3 (9a, b) with CCl4 followed by hydrolysis to give Cp(OC)2Fe-Si(OH)2-SiH3 (10).
