“…The complexation reaction proceeds directly with the Ru precursor RuNOCl 3 (H 2 O) x (Scheme ). Owing to the high moisture sensitivity of organo dilithium compounds,52, 53 the partially hydrolyzed ligands Li x H y mipab, 6 , and Li x H y vipab, 7 , have been isolated from aqueous methanol solutions (dark orange color) and analyzed by X‐ray crystallography, NMR spectroscopy, and ESI mass spectrometry. For unambiguous analytical characterization, the lithiated species Li 2 mipab ( 6 b ) and Li 2 vipab ( 7 b ) were neutralized with an aqueous solution of NH 4 Cl to yield the biscarboxamide ligands (yellow color) H 2 mipab ( 6 a ) and H 2 vipab ( 7 a , Scheme ).…”

“…Essentially it involves the use of heterocumulenes (isothiocyanates, isocyanates) and carbanions readily generated in situ from available alkynes or 1,2-and 1,3-dienes, as key building blocks. The results of these investigations were summarized and analyzed in dissertations [98,148,149] and in recently published reviews and monographs [99,101,[150][151][152][153][154][155][156][157][158][159][160][161][162][163][164][165].…”

“…Organodilithium intermediates have been extensively utilized as dianionic synthons in organic syntheses [20]. Recently, we have shown that organodilithio intermediates can be formed when selected tetrahalobenzenes featuring protons flanked by F/Cl and F/Br atoms are exposed to lithium diisopropylamide (LDA) at low temperatures [9,21].…”
