Abstract
Abstract Thermal reactions of aryl desyl ethers PhCOCH(OAr)Ph (Ar=Ph, p -tolyl) I and II gave 2,3-diphenylbenzo[b]furan 1a,b and phenols 2 and 3 as major products, in addition to small amounts of toluene 4 , benzil 5 , benzoic acid 6 , benzophenone 7 , aryl benzoate 8 and 9 , p -benzylphenol 10 , 2,3,4,5-tetraphenylfuran 11 and 2,3-diphenylbenzo[1,4]dioxin 12a,b . In the presence of isoquinoline as a radical trap, I gave 1-phenylisoquinoline 13 as well as the previous products. Analogously, in addition to diphenylmethane 14 and benzophenone 7 as major products, 1,1,2,2-tetraphenylethane 15 and dibenzhydryl ether 16 as minor products were obtained on heating the benzhydryl desyl ether III . A free radical mechanism has been postulated to take place through the initial homolysis of the C–OAr bond to account for the identified products.
