Two 1,5-diaza-3,7-diphosphacyclooctane (P<sub>2</sub>N<sub>2</sub>) 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 P<sub>2</sub>N<sub>2</sub> ligands (P<sup>Me</sup><sub>2</sub>N<sup>Ph</sup><sub>2</sub> and P<sup>Bn</sup><sub>2</sub>N<sup>Ph</sup><sub>2</sub>)
were synthesized and characterized by <sup>31</sup>P{<sup>1</sup>H}
NMR, <sup>1</sup>H NMR, and elemental analysis, and their corresponding
[Ni(P<sup>R</sup><sub>2</sub>N<sup>Ph</sup><sub>2</sub>)<sub>2</sub>](BF<sub>4</sub>)<sub>2</sub> complexes were synthesized and characterized
by <sup>31</sup>P{<sup>1</sup>H} NMR, <sup>1</sup>H NMR, and electrochemistry.
The structure of the complex [Ni(P<sup>Me</sup><sub>2</sub>N<sup>Ph</sup><sub>2</sub>)<sub>2</sub>](CF<sub>3</sub>SO<sub>3</sub>)<sub>2</sub> was characterized by X-ray crystallography.
