Dihexadecyl Tellurium Oxide Hydrate 0.50 g (0.87 mmol) of hexadecyl teliurium is dissoived in 20 ml of methanol/dichloromethane (1/1, v/v), the solution is cooled to 0°, 0.11 g (1.0 mmol) of ttrt.-butyl hypochlorite are added, and the mixture is stirred for 1 min. The mixture is diluted with 20 ml of dichloromethane, 20 ml of saturated aqueous sodium hydrogen carbonate solution are added, and the mixture is stirred for 5 min. The organic phase is separated, dried with anhydrous sodium sulfate, the solvent is evaporated, and the residue is recrystallized from hexane/ethanol (1/1, v/v) yield 0.49 g (96%) m.p. 92-95°. 

Vesicles of dihexadecyl phosphate speed electron transfer from photoactivated Ru(bpy)3" to methyl viologen, and it was possible to distinguish between reaction on the inner and outer surface of the vesicle. However although the forward step is very rapid so is the back reaction. A modification of this system in which Ru(bpy) is on the inner surface of a dihexadecyl phosphate vesicle will generate hydrogen, provided that the vesicle contains PtO which catalyzes the decomposition of water [168],... 

The hydrogen-generation photo activity of vesicle-stabilized and catalyst-coated colloidal CdS was first demonstrated for dihexadecyl phosphate (DHP) vesicles with Rh as the catalyst and thiophenol (PhSH) as a sacrificial electron donor [see Fig. 5(a)] [4]. Although CdS could be located selectively at the inner or outer surfaces of the vesicles, the symmetrically organized systems were found to be the easiest to prepare most repro-ducibly. No significant effect of the CdS location on the photochemical activity for the H2 generation was observed.
