2,3-Dichloro-5,6-dicyano--benzoquinone (DDQ) in wet ethyl acetate at room temperature catalytically hydrolyzed acyclic acetals effectively and selectively among ethereal functional groups such as dioxoranes, 1,3-dioxanes, oxiranes, TMS- and TBDMS ethers. The mechanism is discussed on the basis ...
This invention also discloses a method of making an alkenyl ether functional polyisobutylene polymer comprising reacting a mixture comprising a polyisobutylene containing at least one hydrolyzable group, an alkenyl ether compound and a solvent. The alkenyl ether functional polyisobutylenes of this invention...

dilation) as the physical phenomena compatible with the theory’s principles. By contrast, Lorentz’s 1909 theory was proposed to explain the same phenomena, but it does it constructively: it derives the relativistic effects from the electromagnetic properties of the ether and its interactions with ...
