A chiral ligand accessible in one step: Synthesis of bis-((R)-(+)-bornyl)acenaphthenequinonediimine and of its zinc and nickel complexes / M. Viganò, F. Ferretti, F. Ragaini, P. Macchi. - In: INORGANICA CHIMICA ACTA. - ISSN 0020-1693. - 483:(2018 Nov 01), pp. 305-309. [10.1016/j.ica.2018.08.049]
Abstract:
A new neutral chiral nitrogen ligand was obtained in one step from commercially available acenaphthenequinone and (R)-(+)-bornylamine. Use of titanium tetraisopropoxide is the key to obtain good yields of the condensed product. Ring strain in the bicyclic system helps in stabilizing the otherwise unstable Alkyl-BIAN type derivative, but is not enough to render the free ligand indefinitely stable. However, complexes of the ligand with the ZnCl2and NiBr2fragment were prepared and are stable. The single crystal X-ray structure of ((R)-(+)-Bornyl-BIAN)NiBr2has been determined.
