Addition of phthalimide and acetone to phosphorylated methylene quinones

New method for synthesis of phosphorylated methylene quinones via bromination of the sterically hindered phenol [prepared via benzylation of secondary chlorophosphines with 4-(methoxymethyl)-2,6-di-tert-butylphenol] with N-bromosuccinimide followed by dehydrobromination with trimethyl orthoformate has been developed. Tertiary phosphine oxides containing the fragment of sterically hindered phenol and amine or acetonyl group have been synthesized for the first time in the reaction of phosphorylated methylene quinones with N- and C-nucleophiles.

SYNTHESIS AND PROPERTIES OF PHOSPHORYLATED 2,6-DI-BUTYL-4-METHYLENE-2,5-CYCLOHEXADIENONES

The products of the oxidation of phosphorylated sterically hindered phenols, proceeding via the intermediate formation of phosphorylated phenoxyl radicals, are phosphorylated 4-methylene-2,5-cyclohexadienones.The reaction of amines (aniline, piperidine) with phosphorylated 4-methylene-2,5-cyclohexadienones results in 1,6-addition products.
