A regioselective zincation of the 2-pyridone and 2,7-naphthyridone scaffolds has been developed. Zincations of the methoxyethoxymethyl (MEM)-protected compounds using TMP2Zn·2MgCl2·2LiCl (TMP = 2,2,6,6-tetramethylpiperidyl) followed by trapping with electrophiles provided functionalized 2-pyridones and 2,7-naphthyridones. I/Mg exchange of iodinated 2-pyridone and 2,7-naphthyridone using i-PrMgCl·LiCl afforded magnesiated intermediates that reacted with electrophiles. A second magnesiation of the 2-pyridone scaffold was achieved by using TMPMgCl·LiCl. Additionally, we report CoCl2-catalyzed cross-couplings of the 1-chloro-2,7-naphthyridines with arylzinc halides.

Quality Control of Bis(dibenzylideneacetone)palladium

A linearly ordered tetraphosphine containing electron-withdrawing substituent groups on the outer phosphorus atoms, meso-bis[{di(3,5- difluorophenyl)phosphinomethyl}phenylphosphino]methane (dpmppmF2), was prepared and reacted with [Pd2(RNC)6](PF 6)2 and Pd(dba)2 to afford tetranuclear palladium complexes, [Pd4(mu-dpmppmF2) 2(RNC)3](PF6)2 (R = 2,6-xylyl (Xyl) (1), 2,4,6-mesityl (2), 2,6-diisopropylphenyl (3) and tert-butyl (4)), which involve an asymmetric {(RNC)Pd4(CNR)2}2+ core supported by two dpmppmF2 ligands in anti-arrangement. Each terminal of the Pd4 chain was capped by terminal isocyanide and a semi-bridging RNC is introduced into one terminal Pd site. Mechanistic investigation suggested that the dipalladium(i) complex, [Pd2(mu- dpmppmF2)2(RNC)2](PF6)2 (R = Xyl (6)), was a key intermediate to trap Pd0 species by the uncoordinated outer phosphine pendants with electron-withdrawing groups. Variable-temperature UV-vis and 31P{1H}, 1H NMR spectroscopic studies demonstrated that the tetrapalladium complexes are quite fluxional in the solution state at high temperature (>20 C) relating to a symmetric structure of [Pd4(mu-dpmppmF2) 2(RNC)2](PF6)2, and the asymmetric solid state structures are retained even in the solution at low temperature (<-60 C). Theoretical calculations with DFT methods on the asymmetric (R = Xyl (1)) and symmetric (R = Xyl (1?)) structures suggested that contribution of Pd0?PdI-Pd0-PdI with 60 cluster valence electrons (CVEs) would be dominant in 1, while the symmetric structure of 1? can be recognized as PdI-Pd 0-Pd0-PdI with 58 CVEs. The new tetraphosphine dpmppmF2 was proven very effective in organizing dynamically flexible tetrapalladium chains.

The reaction of TCNE and TCNQ zwitterionic benzoquinonemonoimine derivatives under basic conditions resulted in HCN elimination to give a tricyanoethenyl derivative – which forms a pi-complex with Pd(0) – or a stable malodinitrile salt, respectively. In the latter case, chemoselective C-alkylation was observed whereas oxidation led to dimerization by C-C coupling. The Royal Society of Chemistry 2011.

Current efforts in this laboratory continue to focus on the preparation of novel complexant motifs for potential use in chemoselective minor-actinide liquid?liquid separations of relevant cations from used nuclear fuel. The present work describes an efficient Pd-catalyzed amination reaction of diversely functionalized 6-bromo-1,2,4-triazinyl-pyridine scaffolds with various amines to afford the opportunity for convergent modulation of complexant electronic and steric properties directly from one substrate towards potentially enhanced solubility in process-relevant solvents. The 21 novel examples presented highlight a unified approach to extensive molecular diversity and provide the ability to further study chelate effects, solubility properties, and complexation efficacy on nonsymmetric, moderately soft-Lewis-basic complexant scaffolds without the incorporation of additional heteroaromatic moieties. Synthetic-method optimization, amine and scaffold scope, as well as a scale-up experiment are presented.
