Ar2Cl2 is found to be a distorted tetrahedron with an Ar2-Cl2 distance of 3.9 ± 0.5 Å and an Ar-Ar bond distance of 4.1 ± 0.6 Å. For Ar3Cl2 there is evidence that two isomers exist. In the low-energy isomer, the three argon atoms form a triangle and the Cl2 bonds with ...

Electrophilic addition to α,β-unsaturated carbonyl compounds is analogous to electrophilic addition to isolated double bonds, except that the electrophile adds to the carbonyl oxygen, the most basic atom in the molecule. After that, the nucleophile adds to the β carbon, and the resulting intermed...
