swurion me L ~L U J ~ rnar suoiimes auring rne reaction. in this way 1.4g (6.4mmol) of sublimed Cr(C0)6 and 1.8g (12.1 mmol) of ( I ) in lOml of dioxane were heated for about 36 h at the b. p. The unconsumed Cr(C0)6 was then removed from the cooled yellowish-brown solution by filtration, the dioxane was evaporated at ca. 40°C and the oily residue was covered with pentane, whereupon a yellow crystalline precipitate of (3) was formed. This was collected on a frit, washed with pentane and sublimed in a high vacuum at ca. 75-80°C. M.p. 112°C (dec.); yield ca. 30%. The 2,4,6-trimethylpyridine complex (4.) was prepared analogously. M. p. 122 "C (dec.); yield ca. 20%.
