New data on the reaction of diethyl hydrogen phosphite with 3,5-di-tert-butyl-4-hydroxybenzaldehyde

3,3′,5,5′-Tetra-tert-butylstilbene quinone and 1,2-bis(3,5-di-tert-butyl-4-hydroxyphenyl)-1,2-bis-(diethoxyphosphinoyl)-ethane were isolated from a mixture of products of the reaction of equivalent amounts of diethyl hydrogen phosphite and 3,5-di-tert-butyl-4-hydroxybenzaldehyde. A scheme of chemical transformations in this reaction system was offered.

The oxidation of 2,6-di-tert-butyl-4-methylphenol with hydrogen peroxide in the presence of potassium iodide gave 3,3′,5,5′-tetra-tert-butyl-4,4′-stilbenequinone which catalyzed liquid-phase oxidation of sodium sulfide with oxygen more efficiently than di

Reaction of esters of PIII acids with 2,6-di-tert-butyl-4-chloromethylidenecyclohexa-2,5-dienone

A reaction of PIII acid esters with 2,6-di-tert-butyl-4-chloromethylidenecyclohexa-2,5-dienone leads to the formation of phosphorylated phosphorus ylides, 3,3’,5,5’-tetra-tert-butylstilbenequinone, and diphosphorylated sterically hindered phenols. The schemes for the formation of these products through the primary key intermediates of betaine and phosphorus ylide structures were suggested.
