Concise preparation of azenes by oxidation of aromatic amines with molecular oxygen in subcritical water
Nermin, Şimşek Kuş
Reaction of organic substrates with molecular oxygen, the most abundant and accessible oxidant, has always been an attractive method for preparation of target molecules. In terms of green chemistry, non-metal-catalyzed oxidation of organic substrates is very attractive. This paper describes a general procedure for synthesis of azenes by oxidation of primary aromatic amines with molecular oxygen (3O2) in subcritical water. The reactions afforded the corresponding azenes in moderate to good yield.
One-step synthesis of substituted isobenzofuran-1(3H)-ones and isobenzofuran-1,3-diones from indane derivatives in subcritical media
Kuş, Nermin Şimşek
Molecular oxygen is one of the most attractive oxidants in organic synthesis because it is highly soluble in subcritical water. In this study, indane derivatives were oxidized to the corresponding isobenzofuran-1(3H)-one with molecular oxygen and isobenzofuran-1,3-dione with a mixture of molecular oxygen and H2O2 in subcritical water. This paper describes a simple, economic, environmentally benign,and general procedure that can be used for the synthesis of substituted isobenzofuran-1(3H)-ones and isobenzofuran-1,3-diones in only one step and without catalyst.
