Abstract:
Neutral hydrocarbon structures containing a planar tetracoordinated carbon atom are proposed on the basis of quantum chemical calculations. The planarity at the central carbon atom is achieved by using aromaticity for stabilizing a positively charged core moiety that contains the planar atom. This charge is compensated by negatively charged cyclopentadienyl rings fused on the structure, leading to neutral structures. These are found to be stable from a dynamic point of view and are potentially synthesizable through carbene chemistry. These structures can lead to new breakthroughs in the chemical structure theory. A family of species derived from this model is also presented.

Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the unhybridized p...
