3a: 2a (0.24 g, 1 mmol) was added to a solution of la (0.41 g, 1 mmol) and NaPF, (0.18 g, 1 mmol) in 20 mL of dry methanol. The solution turned violet after a few minutes and then progressively dark red. The mixture was stirred for 20 hat room temperature. The solvent was removed in vacuo and the red solid was dissolved in 20 mL of THE The solution was filtered, and crystallization from a THF/n-hexane (2/1) solution afforded 0.36 g (48%) of 3a as orange
