Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels. 491-54-3, Name is Kaempferide, molecular formula is C16H12O6. In an article, author is Savvidou, Anatoli,once mentioned of 491-54-3, Safety of Kaempferide.
Synthesis of Benzofuran and Indole Derivatives Catalyzed by Palladium on Carbon
Benzofurans and indoles are key moieties in many natural products and pharmaceuticals. Herein, we describe a cheap and easy-to-execute strategy for the synthesis of benzofurans and indoles, employing Pd/C as the promoter. A variety of substituted allyl-anilines and allyl-phenols were converted into the desired products in good to excellent yields. Recycling of Pd/C was possible up to five cycles, keeping similar levels of reactivity.
