Abstract:
Density functional theory calculations (Becke's three parameter hybrid functional) have been done on a wide range of possible structures for the complexes formed in the reaction between Al(3)O(3) (-) and one or two water molecules. Both energetically competitive structural isomers of Al(3)O(3) (-) (kitelike and distorted rectangle) were considered. The structures of neutral complexes accessed from detachment of the stable anion structures were also optimized. The calculations predict that hydroxide complexes are energetically favored over Lewis acid-base and charge-dipole complexes. For Al(3)O(3) (-)/H(2)O complexes, the kite-based hydroxide and rectangle-based hydroxide are predicted to be nearly isoenergetic, while for Al(3)O(3) (-)/(H(2)O)(2), the rectangle-based dihydroxide emerges as being 0.5 eV more stable than the lowest energy kite-based dihydroxide. The structures of these and their neutrals are used to analyze anion PE spectra of Al(3)O(4)H(2) (-) and Al(3)O(5)H(4) (-) obtained previously [F. A. Akin and C. C. Jarrold, J. Chem. Phys. 118, 5841 (2003)].

Regioselectivity and Stereochemistry of Hydroboration
Hydroboration proceeds in a concerted fashion with the attack of borane on the π bond, giving a cyclic four-centered transition state. The –BH2 group is bonded to the less substituted carbon and –H to the more substituted carbon. The concerted nature requires the simultaneous addition of –H and –BH2 across the same face of the alkene giving syn stereochemistry.
Aldehydes and Ketones with Water: Hydrate Formation
The formation of hydrates is a reversible reaction. Hydrate formation is influenced by steric and electronic factors accompanying the alkyl substituents on the carbonyl group: The rate of hydrate formation increases with a decrease in the number of alkyl groups attached to the carbonyl carbon. Hence,...
