15. Structural characterization of the novel organomanganese compounds by ESR and magnetic measurements will be the subject of a forthcoming study.
16. 2 in 25 mL of THF was added 1 mmol (NCN)Li dissolved in 5 mL of THF. The reaction mixture was stirred until a clear solution was obtained. To this solution 0.5 mmol CuCl was added and the mixture was cooled to 5 °C. Subsequently 10 mmol of the corresponding bromide and 10 mmol of the Grignard were added. The reaction mixture was stirred for an additional 15 min. at 5 °C and hydrolyzed with 50 mL 4M HCl. After work-up (pentane extraction and flash distillation) the products were isolated as colourless liquids; isolated yields of pure products are given in Table I. The products were identified by comparison of their GC, MS and NMR data with those of authentic samples.
