Boron-containing polycyclic aromatic

Early research on boron-containing polycyclic aromatic hydrocarbons ( -PAHs) and their monocyclic archetypes was motivated in many cases by a general desire to understand the impact of an electron-deficient element such as boron on the properties of a conjugated cyclic array. A variety of different polycyclic systems have been conceived in which neutral or anionic sp -hybridized boron centers could act as surrogates for cationic or neutral carbon centers, respectively... [Pg.251]

The addition of methanolic alkali or boron trifluoride methanol [97,99] as a modifier has been recommended for the extraction of polycyclic aromatic hydrocarbons from soils containing a high proportion of humic acids. [Pg.96]
