Article Abstract
5,10,23-Trimesityl-substituted [24]hexaphyrin(1.1.0.0.1.0) was synthesized as a stable antiaromatic molecule by base-catalyzed twofold SAr reaction and was reduced to the corresponding [26]hexaphyrin, which was an unstable aromatic molecule because it easily oxidized to the [24]hexaphyrin. The [24]hexaphyrin served as a ligand to give the bis-Pd complex and tris-Rh complex with unique structures. The former complex has two square-planar-coordinated Pd ions bridged by an acetate anion and shows a strong paratropic ring current, while the latter complex has three Rh ions coordinated with two pyrrolic nitrogen atoms and two carbonyl groups, but one carbonyl group is shared with two Rh ions in a unique manner.

The reaction of the diborabenzene (DBB) nickel(0) pogo-stick complex [(η-DBB)Ni(CO)] () with a large excess of [Ni(CO)] yields the dark green, unstable dinickel(0) complex [(η-DBB)Ni(μ-CO)Ni(CO)] (), which loses one CO ligand to yield the purple, bimetallic Ni half-sandwich complex [(η-DBB)Ni(μ-CO)(η-CO)] (). The addition of the chromium aminoborylene complex [(OC)Cr{BN(TMS)}] (TMS = trimethylsilyl) to does not result in the expected borylene transfer but in the formation of the black Ni-Cr complex [(η-DBB)Ni(μ-CO)Cr(CO)] (), alongside the dimeric iminoborane [(TMS)BN(TMS)] (), which results from the rearrangement of the released BN(TMS) aminoborylene moiety. Furthermore, the oxidative addition of methyl triflate (MeOTf) to leaves the (η-DBB)Ni moiety intact and provides the ionic Ni half-sandwich complex [(η-DBB)NiMe(CO)]OTf (), while reaction with pentaphenylborole (PPB) yields the unique, dark-blue, unsymmetrical sandwich complex [(η-DBB)Ni(μ-CO)(η-PPB)] ().

The search for stable compounds containing an antiaromatic cyclic 4π system is a challenge for inventive chemists that can look back on a long history. Here we report the isolation and characterization of the novel 4π-electron tetrasilacyclobutadiene, an analogue of a 4π neutral cyclobutadiene that exhibits surprising features of a Möbius-type aromatic ring. Reduction of RSiCl (R = (Pr)PCH) with KC in the presence of cycloalkyl amino-carbene (cAAC) led to the formation of corresponding silylene 1.

Porphyrinoids in the 20π-electron state have been extensively studied from the fundamental viewpoint of investigating their structure-antiaromaticity relationships. However, most of the 20π porphyrinoids are highly distorted and unstable in air, which hinder the comprehensive analysis of paratropic ring-current effects derived from planar π-electron systems. Herein, we present the first examples of antiaromatic Sn(IV) complexes of 5,10,15,20-tetraaryl-5,15-diazaporphyrinoids (SnXTADAPs), prepared by the complexation of the corresponding freebases with Sn(II) chloride under aerobic conditions and subsequent metathesis of the axial ligands, that show paratropic ring-current effects.

1,3,4,6-Tetraphenylpentalene (PhPn) has been synthesised by chemical oxidation of the corresponding pentalenide complex Mg[PhPn] with iodine. PhPn is a rare example of a room-temperature stable hydrocarbon that is antiaromatic by Hückel's rule and has been fully characterised by NMR and UV-vis spectroscopy, mass spectrometry as well as single-crystal X-ray diffraction. Quantum chemical studies including nucleus-independent chemical shift (NICS) and anisotropy of the induced current density (ACID) calculations showed the existence of an 8π antiaromatic core decorated with four independent 6π aromatic substituents.

An air- and moisture-stable hydrocarbon radical with four six- and three five-membered rings alternately fused to a heptacycle was obtained by ortho fusion in a suitably ortho,ortho'-substituted diphenylfluorene and subsequent re-establishment of the conjugation. The radical was obtained in five consecutive steps from commercially available starting materials with a total yield of 34 %; key steps are Suzuki couplings and cyclizing SAr reactions. Mesityl substituents at the five-membered rings ensure the stability of the radical.
