Sanz, Roberto published the artcileDioxomolybdenum(VI)-catalyzed reductive cyclization of nitroaromatics. Synthesis of carbazoles and indoles, Category: indole-building-block, the publication is Advanced Synthesis & Catalysis (2007), 349(4+5), 713-718, database is CAplus.
Reductive cyclization of nitrobiphenyls and nitrostyrenes to carbazoles and indoles, resp., is carried out by triphenylphosphine under mild conditions catalyzed by a dichlorodioxomolybdenum(VI) complex. A one-pot procedure for the synthesis of regioselectively functionalized indoles has been developed from com. available o-nitrobenzaldehydes and phosphoranes.
