Syntheses of Organofunctional Siloxanes containing Metal-ligating Sidechains

A range of tri-, tetra-, and penta-siloxanes of general formula Me3SiOnSiMe3 (R=vinyl, n=1-3; R=an alkyl chain terminated by the potential metal-ligating entities CH=CH2, Ph, CN, cyclohexenyl, pyridine, and PPh2, n=1 or 2) have been synthesised from commercially avilable dichlorosilanes by one of three procedures.The products are air-stable oils with the exception of the pyridine- and phosphine-functionalised compounds which react vigorously with oxygen, and the spectroscopic properties of corresponding organofunctional siloxanes are very similar showing little dependence on n.
