    • Experimental procedures and characterization of new compounds are as follows. 1b: THF (20 mL) at -78ÆC was added slowly via a cannula to a mixture of KN(SiMe3)2 (1.54 g, 7.70 mmol) and 8 (1.33 g, 7.33 mmol) with stirring. Methylene chloride (10 mL) was added slowly at -78°C. The mixture was stirred at -78°C for 2 h and then warmed slowly to 25°C for 10 h. The solvent was removed under reduced pressure, and the residue was extracted with pentane (2 × 25 mL, Removal of the solvent from the extracts gave a dark red oil, which was distilled (32°C at 0.01 Torr) to afford 1b as a colorless liquid (0.40 g, 35% yield, IR (film; cm-1, 3075, 3014, 1617, 1504, 1435, 1388, 1266, 740, 697, 678.
