Synthesis, molecular structures of alkyliminophenols and studies of their derivatives 1,3-oxazepine-4,7-diones

A series of alkyliminophenols (HOC6H4)CNCnH2n+1CH3 where n are even parity number ranging from 0 to 16 have been isolated and their molecular structures were studied. The molecular structure of 3-((dodecylimino)methyl)phenol has further been ascertained via the single-crystal X-ray diffraction analysis in which the compound possesses space group of P21/c. Crystal structures also revealed that the dodecyl chain in this molecule was fully extended in zig-zag form. The novel derivatives 1,3-oxazepine-4,7-diones with general formula (HOC6H4)CONCnH2n+1CHCH(CO)2 in which n are even parity numbers ranging from 2 to 18 have been synthesized from the reaction of 3-((alkylimino)methyl)phenol with maleic anhydride.
