A facile method for the one-pot synthesis of 1,2-diarylindoles under transition-metal-free conditions is described. Cyclohexanones were used as the aryl sources via the dehydrogenative aromatization process. One C-C and two C-N bonds were selectively formed via a domino reaction. This protocol provides a convenient approach for the construction of valuable bioactive 1,2-diarylindoles from readily available cyclohexanones, α-hydroxyketones and anilines.

A new variant of the Interrupted Feist-Benary (IFB) reaction uses α-tosyloxyacetophenones as electrophiles and proceeds in good yields and excellent enantioselectivities.
Novel preparation of polymer-supported iodobenzene and its synthetic utility as a recyclable reagent with m-chloroperbenzoic acid
Suzuki, Yuhsuku,Togo, Hideo
experimental part, p. 2355 - 2360 (2010/09/18)
Three novel polymer-supported iodobenzene compounds A0, A 6, and A10 were prepared from the reaction of commercially available cross-linked poly(p-chloromethyl)styrene with m-iodobenzylalcohol, 6-(m-iodobenzyloxy)-1-hexanol, and 10-(m-iodobenzyloxy)-1-decanol. Their catalytic reactivity and reusability for the oxidative α-tosyloxylation of ketones and the cyclization of N-methoxy-2-arylethanesulfonamides in the presence of m-chloroperbenzoic acid (mCPBA) were confirmed to provide -tosyloxyketones and N-methoxy-3,4-dihydro-2,1-benzothiazine-2,2-dioxides, respectively, in good yields.
