This paper describes a one-step, room temperature synthesis utilizing ultrasonic energy of a coaxially stacked poly(phthalocyanato) germanium oxide ([Ge(Pc)O].) from Ge(Pc)C12. The synthesis is conducted in the presence of a sodium chalcogenide. Based on photoacoustic FTi.r. and u.v.-vis. spectroscopic analysis, the mechanism of the [Ge(Pc)O], formation is proposed. The use of isotopic H20/D20 exchange is also utilized in an effort to reveal the role of traces of water present during the polymerization reaction

The synthetic route to polythiiranes bearing side chain biphenyl groups is described. [(4- Biphenyl)methylthio]methylthiirane afforded relatively low molecular weight polymers in 50% yield, while (4-biphenyl)methyl 2-[(2,3 epithiopropyl)-thio]ethanoate afforded high molecular weight polymers in high yields.

Poly(vinyl pyridine)-supported ceric(IV) complex can be easily prepared. It catalyses nucleophilic ring opening of epoxides in alcohols under mild conditions with high regio- and stereoselectivity. The reaction work-up is easy and the catalyst can be reused several times without its activity changing appreciably. Regeneration of the catalyst is easily achieved.
