Abstract | {The synthesis of a series of C-aryl-N-[2-(hydroxymethyl)phenyl]nitron 5 (that can also exist under certain conditions as isomeric 1-hydroxy-2-aryl-1,2-dihydro-4H-3,1-benzoxazines 8), via 2-(hydroxyamino)benzyl alcohol, 4, and their subsequent reactions with oxybis(diphenylborane), (Ph2B)(2)O, leading to the 5-(arylmethylene)-7,7-diphenyl-6,8-dioxa 5-azonia-7-borata-5H-6,7,8,9-tetrahydrobenzocycloheptenes 6 are described. Crystals of 1-hydroxy-2-(4-methoxyphenyl)-1,2-dihydro-4H-3,1-benzoxazine, 8b, are monoclinic |
