Abstract
A metal-free protocol for direct aryl-aldehyde Csp(2)-Csp(2) bond formation via a PhI(OAc)2-mediated intramolecular cross-dehydrogenative coupling (CDC) of various 2-(N-arylamino)aldehydes was developed. The novel methodology requires no need of preactivation of the aldehyde group, is applicable to a large variety of functionalized substrates, and most of all provides a convenient approach to the construction of biologically important acridone derivatives.

Abstract
An efficient route to constructing C–S bonds has been developed by TBHP ( tert-butyl hydroperoxide) mediated C–H thiolation of tetrahydrofuran with disulfides. This route is promoted by catalytic amounts of Na2CO3 and gives various tetrahydrofuran-containing sulfides in moderate to high yields.

Abstract
Cross dehydrogenative coupling reactions occurring via base-promoted homolytic aromatic substitutions (BHASs) are reported. Fluorenones and xanthones are readily prepared via CDC starting with readily available ortho-formyl biphenyls and ortho-formyl biphenylethers, respectively. The commercially available and cheap tBuOOH is used as an oxidant. Initiation of the radical chain reaction is best achieved with small amounts of FeCp(2) (0.1 or 1 mol %).
