WebBoth 9-methoxy-9-phenylfluorene and 9-phenyl-9-fluorenol can be converted to 9-bromo-9-phenylfluorene by treatment with 48% hydrobromic acid (HBr). 5 Both the stability 14 and rigid steric bulk of the 9-phenylfluoren-9-yl group have increased significantly the utility of amino acids N-protected in this way as chiral educts for asymmetric synthesis. Fluorene /ˈflʊəriːn/, or 9H-fluorene is an organic compound with the formula (C6H4)2CH2. It forms white crystals that exhibit a characteristic, aromatic odor similar to that of naphthalene. It has a violet fluorescence, hence its name. For commercial purposes it is obtained from coal tar. It is insoluble in water and soluble in many organic solvents. Although sometimes classified as a polycycli… ha meaning in india
