## Synthesis and characterization of fluorinated fullerene C6o have been reported by several groups [l-8]. Mass spectroscopy revealed that a stable fluorinated product was C60F36 [6] and a main product obtained under UV irradiation was C6oF48 [7]. Mass spectroscopic studies suggest that C6o is flu

In a series of 2-X-fluorobenzenes, the relative signs between 'J(CF) and the corresponding 4J(HF) couplings were determined. In most cases like signs were found. However, for the coupling pathway involving the X group, unlike signs were found for X = CN, NCS and NO,. For other electronegative substi
