van der Vlugt, Jarl Ivar published the artcileCationic and neutral NiII complexes containing a non-innocent PNP ligand: formation of alkyl and thiolate species, Computed Properties of 338800-13-8, the publication is Dalton Transactions (2009), 1016-1023, database is CAplus and MEDLINE.
The synthesis and characterization of a series of cationic and neutral Ni-complexes with the non-innocent pincer ligand (HL = 2,6-bis(di(tert-butyl)phosphinomethyl)pyridine) is discussed. Starting with the dicationic complex [Ni(L)(NCMe)](BF4)2 (1), a small series of dicationic and monocationic NiII complexes has been prepared Substitution with tert-Bu isocyanide and azide occurs readily in MeCN solution IR spectroscopy provided a practical handle to access the formal valence state of the ligand. For the mono- and dicationic tert-Bu isocyanide derivatives the main vibrational bands in the IR spectra were reproduced quant. by DFT theor. calculations, showing good agreement with the exptl. observed Δν upon dearomatization of the ligand backbone. Using a selective dearomatization-reprotonation methodol. the mononuclear Ni-thiolate derivatives are cleanly generated and their structures have been determined by X-ray crystal structure determination Alternatively, starting from the monocationic species [Ni(L)Cl]BF4, neutral alkyl derivatives are easily available in a two-step procedure, and these species have been spectroscopically characterized.
