Reaktionsschritte

To a solution of α-(1-phenylethenyl)-2,4-dichlorobenzenemethanol (4 g) in toluene (100 ml) was added barium manganate (5 g) and the resulting mixture heated at reflux under an atmosphere of nitrogen for a period of 12 hours. The reaction mixture was cooled, filtered and concentrated under reduced pressure to yield 1-(2,4-dichlorophenyl)-2-phenylpropen-1-one, (δ (CDCl3), 5.75 (1H,s), 6.3 (1H,s) and 7.25-7.60 (8H,m)) as a gum (4.3 g) having the formula: ##STR27##
