D. Doud, Kyle A. Grice, Alyssia M. Lilio, Candace S. Seu, Clifford P. KubiakTwo 1,5-diaza-3,7-diphosphacyclooctane (P2N2) ligands with alkyl-substituted phosphines have been
synthesized
via a versatile method that allows for improved control of the phosphine
substituent. The methyl- and benzyl-substituted phosphine P2N2 ligands (PMe2NPh2 and PBn2NPh2)
were synthesized and characterized by 31P{1H}
NMR, 1H NMR, and elemental analysis, and their corresponding
[Ni(PR2NPh2)2](BF4)2 complexes were synthesized and characterized
by 31P{1H} NMR, 1H NMR, and electrochemistry.
The structure of the complex [Ni(PMe2NPh2)2](CF3SO3)2 was characterized by X-ray crystallography.
