Oral disease is one of the most common diseases found in dogs. [ 1 ] [ 2 ] It is caused by the buildup of various anaerobic bacteria in the mouth which forms plaque , eventually hardening into tartar on the teeth along the gum line, and is related to the development of gingivitis . [ 3 ]
This difference is partly related to the lower symmetry of the individual pyridine molecule (C 2v vs D 6h for benzene). A trihydrate (pyridine·3H 2 O) is known; it also crystallizes in an orthorhombic system in the space group Pbca, lattice parameters a = 1244 pm, b = 1783 pm, c = 679 pm and eight formula units per unit cell (measured at 223 K).
Pyrylium salts are easily produced from simple starting materials through a condensation reaction. [2]Pyrylium salts with aromatic substituents, such 2,4,6-triphenylpyrylium tetrafluoroborate, can be obtained from two moles of acetophenone, one mole of benzaldehyde, and excess tetrafluoroboric acid.

For example, the aromatic species 1 can be reduced to 2 with a relatively small penalty for forming an antiaromatic system. The antiaromatic 2 does revert to the aromatic species 1 over time by reacting with oxygen in the air because the aromaticity is preferred. [15] The loss of antiaromaticity can sometimes be the driving force of a reaction.

Hückel's rule can also be applied to molecules containing other atoms such as nitrogen or oxygen. For example pyridine (C 5 H 5 N) has a ring structure similar to benzene, except that one -CH- group is replaced by a nitrogen atom with no hydrogen. There are still six π electrons and the pyridine molecule is also aromatic and known for its ...
