Abstract

889-892<span style="font-size:12.0pt;font-family: " times="" new="" roman";mso-fareast-font-family:"times="" roman";mso-ansi-language:="" en-in;mso-fareast-language:en-in;mso-bidi-language:ar-sa"="" lang="EN-IN">On treatment with NaN3/TFA, some E-3-benzylideneflavanones yield 3-benwylchromones with the loss of 2-aryl group as the corresponding aniline, a plausible mechanistic path for which has been delineated. An acid-catalysed skeletal rearrangement of some E-3-benzylideneflavanones also takes place.</span
