12. 3 (0.65 g, 1.32 mmol) in toluene (15 ml). The reaction solution color changed from yellow to deep green and the fine white deposit of NaI was observed. The red InI precipitates from the reaction mixture in 5 min. Toluene was replaced with hexane and solution was separated from the solid by filtration. Cooling of the hexane solution resulted in the formation of dark green crystals of 1. The total yield is 0.49 g (56.6%).
13. The imQ (0.5 g, 1.32 mmol) dispersion in dimethoxyethane (15 ml) was added to InI [14] (0.16 g, 0.66 mmol) dispersion in dimethoxyethane (15 ml) at -20 °C and reaction mixture was stirred till full disappearance of InI. The color of reaction solution turned from wine red to deep green. After reaction was finished, dimethoxyethane was evaporated under vacuum conditions and hexane was added. After slow evaporation of hexane solution, dark green crystals of 1 were obtained. The total yield is 0.40 g (69.3%).
14. 4 [14] (0.324 g, 0.88 mmol) dispersion in toluene (15 ml). During the reaction color of solution turned from wine red to deep green and the wine red crystalline product formed which was characterized as complex 2 (see Ref. [10]).
