Transition-metal (phosphinoalkyl)silanols: Ligand functionality designed for surface attachment. Chemistry of P-coordinated ((diphenylphosphino)alkyl)dimethylsilanol complexes of ruthenium, rhodium, and indium

The Si-C bond in the phosphinomethysilane Ph2PCH2SiMe2H (1) is very sensitive to cleavage by H2O, MeOH, or HCl, affording (Me2SiO)2O, SiHMe2(OMe), or SiHMe2Cl respectively, together with PPh2Me. By contrast, the ethyl congener Ph2PCH2CH2SiMe2H (2) of 1, which is unaffected by H2O or MeOH, gives Ph2PCH2CH2-SiMe2Cl on treatment with HCl. The phosphonium salts [Ph2P(Me)(CH2)nSiMe2H][1] (3, n = 1; 4, n = 2) are formed quantitatively on treatment of 1 or 2 with MeI. A number of transition metal complexes react with silanes 1 and 2 to yield products in which the Si-H bond remains intact: thus [Ru(η6-arene)(μ-Cl)Cl]2 with 1 or 2 gives [Ru(η6-arene)Cl2(L)] (arene = p-cym [cym = cymene, i.e. isopropyltoluene], 5, L = 1; arene = p-cym, 6, L = 2; arene = C6Me6,7, L = 2; arene = C6H6, 8, L = 2), [RuCpCl(PPh3)2] (Cp = η5-C5H5) gives [RuCpCl(PPh3)(L)] (9, L = 1; 10, L = 2), [Ru2Cp2(C2Ph2)(CO)3] with 2 gives [Ru2Cp2(CO)3(PPh2CH 2CH2SiMe2H)] (11), and [M(η5-C5Me5)(μ-Cl)Cl]2 with 2 gives [M(η5-C5Me5)Cl2(PPh 2CH2CH2SiMe2H)] (12, M = Rh; 13, M = Ir). The Si-H bonds in complexes 6 and 12 are sensitive to hydrolysis that effects transformation of the monodentate phosphinoalkylsilane into a dangling silanol, i.e. [Rh(η5-C5Me5)Cl2(PPh 2CH2CH2SiMe2OH)] (14) (from 12), for which the X-ray crystal structure is described, and [Ru(η6-cym)Cl2(PPh2CH2CH 2SiMe2OH)] (15) (from 6). Nucleophilic displacement at Si in compounds 5 and 6 is general so that treatment of 5 with HX gives [Ru(η6-cym)Cl2(PPh2CH2SiMe 2X)] (16, X = Cl; 18, X = OMe; 21, X = O(CH2)13CH3) while the products [Ru(η6-cym)Cl2(PPh2CH2CH 2SiMe2X)] (17, X = Cl; 19, X = OMe; 20, X = OEt; 22, X = OCH2CH2C(Me)=CH2; 23, X = OC11H17) are formed from 6. The unusual reactivity of the Si-H bond in this family of complexes is further illustrated by the isolation of [Ru(η6-cym)Cl(PPh2CH2CH 2SiMe2F)2] [PF6] (24) from a reaction in which the only source of F is the classically unreactive PF6- ion.
