✦ Synopsis

dropwise at such a rate that THF distilled over slowly. The evolution of hydrogen gas was followed by means of a wet-test meter. When the addition was complete and 5 L of hydrogen had evolved, the slurry was concentrated to approximately 400 mL, cooled slightly, and diluted with hexane to I L. A white precipitate formed. The solution was filtered while hot. The white precipitate was then washed with hexane and air-dried to afford K( 1) as a white solid (54 g, 93% yield), which was used to prepare the other metal derivatives. TI( 1) and [Co( I)>] 3 : these compounds were prepared by adding an aqueous solution of TINO, or CO(NO,)~ to a methanolic solution of K( 1). The precipitated products were isolated by filtration, washed with water, then with methanol, and air-dried. The materials were recrystallized from toluene. Correct elemental analyses (C, H, N) were obtained.
