Gas phase generation and cyclisation reactions of some o-substituted phenyl radicals
Cadogan,Hutchison,McNab
, p. 7747 - 7762 (2007/10/02)
Flash vacuum pyrolysis of the allyl esters 2 (X=O, S, CH2, CO) at 900°C (10-2 Torr) gives dibenzofurans, dibenzothiophenes, fluorenes, and fluorenones respectively as the major products. The mechanism involves the phenyl radical intermediates 1 which equilibrate by intramolecular hydrogen transfer via six-membered transition states, prior to cyclisation.
Methyl substituted thioxanthones and thioxanthone-10,10-dioxides
Brindle, Ian D.,Doyle, Paul P.
, p. 1869 - 1871 (2007/10/02)
The preparation of all four monomethylthioxanthones and their corresponding dioxides is described.A previously published synthesis of the 2- and 3-methylthioxanthones by Gilman and Diehl has been shown to produce the 2- and 4-methyl isomers.
