166
TL;DR: This review provides a comprehensive overview of metallaromatic chemistry and focuses on not only the six major classes of metallaaromatics, including the main-group-metal-based metallaarate compounds, but also other types, such as metallacyclobutadienes and met allacyclopropenes.

Abstract: Since the prediction of the existence of metallabenzenes in 1979, metallaaromatic chemistry has developed rapidly, due to its importance in both experimental and theoretical fields. Now six major types of metallaromatic compounds, metallabenzenes, metallabenzynes, heterometallaaromatics, dianion metalloles, metallapentalenes and metallapentalynes (also termed carbolongs), and spiro metalloles, have been reported and extensively studied. Their parent organic analogues may be aromatic, non-aromatic, or even anti-aromatic. These unique systems not only enrich the large family of aromatics, but they also broaden our understanding and extend the concept of aromaticity. This review provides a comprehensive overview of metallaaromatic chemistry. We have focused on not only the six major classes of metallaaromatics, including the main-group-metal-based metallaaromatics, but also other types, such as metallacyclobutadienes and metallacyclopropenes. The structures, synthetic methods, and reactivities are described, their applications are covered, and the challenges and future prospects of the area are discussed. The criteria commonly used to judge the aromaticity of metallaaromatics are presented.

TL;DR: Aromaticity is one of the most deeply rooted concepts in chemistry as mentioned in this paper . But why, if two-thirds of existing compounds can be classified as aromatic, is there no consensus on what aromaticity is?
Program Package for the Calculation of Origin-Independent Electron Current Density and Derived Magnetic Properties in Molecular Systems.
TL;DR: SYSMOIC as mentioned in this paper is a program package for the calculation of the origin-independent current density induced at first order by an external magnetic field in planar and nonplanar molecular systems.

Metalla-aromatics: Planar, Nonplanar, and Spiro.
TL;DR: In this paper, a series of metalla-aromatics with transition metals involved in conjugation and electron delocalization of aromatic compounds are presented. But, unlike the planar metalla aromatics, the non-planar aromatic compounds are not necessarily planar.

From osmium hydrido vinylidene to osmacycles: the key role of osmabutadiene intermediates.
TL;DR: Mechanistic analysis indicates that 1 reacted with HC≡CCH(OH)C≡CH to yield osmabenzene 4, in which the alkynol acted as a C(5) fragment to cyclize with 1, and that these reactions and the previous formal [3+3] cycloadditions between 1 and HC=Ph, Et, and vinyl all go through similar osm abutadiene intermediates.
