Article abstract of DOI:10.1002/hlca.19820650702

Addition of dialkyl phosphites to the nitrone 6, formed in situ from the oxime 5 and formaldehyde gave the hydroxylamines 7 (86percent) and 8 (88percent), which reacted with p-benzoquinone in the presence of ethylene via the C-dialkoxyphosphonoylnitrones
