General procedure: Representative procedure for 17: A Schlenk tube was charged with 2 (400mg, 2.03mmol), dry THF (10mL), anhydrous cobalt(II) chloride and a stirring bar. In a separate Schlenk tube, a solution of lithium diisopropylamide (LDA) was prepared in THF (25mL) from diisopropylamine (700muL, 5.0 mmol) and n-butyl lithium (3.15mL of a 1.6M solution in hexane, 5.0 mmol). The LDA-solution was added under protection from air to the solution of 2 and CoCl2. After the mixture has been stirred overnight, all volatile materials were removed on a vacuum line. The Schlenk vessel was transferred into the glove-box and the dark colored solid residue was dissolved in a small volume of dry dichloromethane. Layering the solution with dry n-hexane afforded brown single crystals of the product., 34946-82-2

The copper(II) complexes with terpy ligand, [Cu(terpy)(ClO4)2(H2O)] (1) and [Cu(terpy)2](CF3SO3)2¡¤2H2O (2), were synthesized by modification of a previously described method for the preparation of [Cu(terpy)(H2O)](CF3SO3)2 complex [42]. The solution of 1.0mmol of terpy (233.3mg) in 2.0mL of methanol for 1 and ethanol for 2 was added slowly under stirring to the solution containing 1.0mmol of the corresponding copper(II) salt (370.5mg of Cu(ClO4)2¡¤6H2O (1) and 361.7mg of Cu(CF3SO3)2 (2)) in 5.0mL of water. The reaction mixture was stirred at room temperature for 3h. The blue crystals of 1 and 2 suitable for single-crystal X-ray analysis were grown by slow evaporation of the resulting solutions at room temperature. These crystals were filtered off and dried at ambient temperature. The yield (calculated on the basis of terpy) was 73% (375.0mg) for 1 and 78% (337.1mg) for 2.

General procedure: The solution of CuX2 salt (0.5 mmol, 120.8 mg of Cu(NO3)23H2Ofor 3a/b and 180.8 mg of Cu(CF3SO3)2 for 4) in 5.0 mL of ethanol (3aand 4) or methanol (3b) was mixed with the solution of anequimolar amount of 1,7-phen (90.1 mg) in 5.0 mL of ethanol (3aand 4) or methanol (3b). After addition of 1,7-phen, a solutionchanged color from blue to green, and no formation of metalliccopper was observed. The reaction mixture was stirred at roomtemperature for 3-4 h and then left at room temperature to slowlyevaporate. Crystals of compounds 3a/b were obtained from themother solution, while those of compound 4 were obtained after recrystallization of the solid product formed from the reactionmixture in 15.0 mL of acetonitrile. These crystals were filtered offand dried at ambient temperature. Yield (calculated on the basisof 1,7-phen): 65.7 mg (54%) for 3a, 74.2 mg (61%) for 3b and94.1 mg (57%) for 4., 34946-82-2
