Oxidation of 2'-hydroxy-3'-nitrochalcones with thallium(III) nitrate gives (Z)-2-phenylmethylene-7-nitrobenzofuran-3(2H)-one derivatives, rather than the more usual 1,2-diaryl-3,3-dimethoxypropan-1-ones or the corresponding isoflavones. - Keywords: Oxidat
THE EFFECT OF NITRO GROUPS ON OXIDATIVE CYCLISATION OF CHALCONES BY THALLIUM(III) NITRATE(TTN)
Varma, Rajender S.,Varma, Manju
, p. 3007 - 3008 (2007/10/02)
2'-Hydroxy-3'-nitrochalcons on oxidation with thallium(III)nitrate do not give rearranged intermediates that can give isoflavons, instead cyclisation gives benzylidenebenzofuran-3(2H)-one derivates.
