Formation of phosphoranes and related compounds in trialkyl phosphite deoxygenations of 2,6-dimethylaryl 2-nitrophenyl ethers and 2,6-dimethylaryl-2-nitrophenylmethane
Abstract
Trialkyl phosphite deoxygenation of 2,6-dimethylphenyl 2-nitrophenyl ether gives the aminotextroxyphosphorane (IV) and that of 2-nitrophenyl-2,4,6-trimethylphenylmethane gives diethyl o-(2,4,6-trimethylphenylamino)benzylphosphonate, which novel products support the intermediacy of a spirodiene in these reactions.
