“…A transformation of the latter to 1,2-diacylbenzenes was first reported by Kotali and Tsoungas 9,10 using lead tetraacetate (LTA) and its mechanism was studied by Katritzky et al 11 The use of iodobenzene diacetate (IBD), 12 polystyrene-supported IBD 13 or cross-linked poly[styrene(iodoso diacetate)] 14 as oxidants in this transformation, gives comparable results. Other methods of synthesizing 1,2-diacylbenzenes are: palladium(II)-catalyzed direct acylation of acetophenone N-Boc hydrazones with aldehydes via C-H bond activation 15 and Pd-catalysed oxidative C-H bond coupling of acetophenone O-methyl oximes and aldehydes to give 1,2-diacylbenzene O-methyl oximes which are then hydrolysed, 16 oxidation of benzhydrols with selenium dioxide, 17 of benzofurans with LTA, 18 and of 2-ethylacetophenone with potassium permanganate, 19 or acylating benzene with 2-acetylbenzoyl chloride. 20 It is worth noting that 2,3-diacylnaphthalenes are known, 21 while their 1,2-diacyl regioisomers are hitherto unreported.…”
