Reaction of Monothio-derivatives of 2-Heteroarylideneindene-1,3(2H)-diones with Quinones
Buggle, Katherine,Power, Joseph
, p. 1070 - 1075 (2007/10/02)
The reaction of 2,3-dihydro-2--3-thioxoinden-1-one (5) with 1,4-benzoquinone and with 1,4-naphthoquinone in alcohols afforded thiobenzoylindolizinoquinones (7) and (12) which were characterised by spectroscopy and by oxidation and redu
