  • Publication number: 20230203068
    Abstract: Two classes of cyclic tin compounds, trioxa-aza-1-stannabicyclo-[3.3.3]-undecanes, also referred to as stannatranes, and tetraaza-1-stannabicyclo-[3.3.3] undecanes, also referred to as azastannatranes, are described, as are methods for their preparation. These cyclic tin compounds are resistant to rearrangement and the generation of dialkyltin impurities is not observed during the synthesis, purification or deposition of these compounds to form oxostannate films.

  • Publication number: 20230098287
    Abstract: A new class of compounds known as chalcogenosilacyclopentanes is described. These compounds are five-membered ring structures containing a silicon-selenium or silicon-tellurium bond, as shown in Formulas (I) and (II). In these compounds, the substituents on the silicon and on the ring carbons may be hydrogen, alkyl, alkoxy, aromatic, or ether groups. The chalcogenosilacyclopentane compounds undergo ring-opening reactions with hydroxyl and other protic functionalities and may be used to prepare substrates that are amenable to thin film deposition techniques such as ALD and CVD.
