DOI: 10.1016/j.jorganchem.2019.02.019
Abstract: Abstract An acyclic flexible bis(α-iminopyridine) ligand has been employed for the stabilization of chlorostannyliumylidene and a tin(II) dication. The syntheses involve the abstraction of chloride from the tin dichloride precursor using trimethylsilyl trifluoromethane sulfonate. The… read more here.

DOI: 10.1021/acs.organomet.7b00597
Abstract: The formal two-electron reduction of the cyclo-tri(phosphonio)methanide dication 12+ results in a ring-opening reaction via C–P bond cleavage to yield the unique phosphanyl-functionalized carbodiphosphorane 2. In situ spectroelectrochemical investigations of the reduction of dication 12+… read more here.

DOI: 10.1021/acs.orglett.5c02924
Abstract: Unlike aromatic porphyrins, conventional oxidative coupling reactions do not yield dimeric or oligomeric antiaromatic porphyrinoids. We describe here the first example of a β-β-linked antiaromatic expanded porphyrinoid through a novel synthetic strategy. It contains two… read more here.

DOI: 10.1021/acsomega.8b03192
Abstract: Syntheses and structures of anionic arylphosphate monoesters [ArOP(O)2(OH)]− (Ar = 2,6-CHPh2-4-R-C6H2; R = Me/Et/iPr/tBu) with different counter cations are reported. The counter cations were varied systematically: imidazolium cation, 2-methyl imidazolium cation, N-methyl imidazolium cation, N,N′-alkyl… read more here.

DOI: 10.1021/jacs.2c00493
Abstract: The synthesis and isolation of one of the few examples of a π-extended diamagnetic phenazine dication have been achieved by oxidizing a phenanthrene-based dihydrophenazine precursor. The resulting dication was isolated and fully characterized, highlighting an… read more here.
