Abstract:
Wedge-shaped amphiphilic derivatives of 1,3-dipyrrolyl-1,3-propanedione boron complexes, with one or no aliphatic chains attached at one aryl moiety and three hydrophilic chains at the other, exhibited formation of assembled structures in aqueous solutions. UV/vis, fluorescence and DLS analyses suggested that the wedge-shaped amphiphiles exist in assembled modes in the solution state, and TEM measurements revealed that a balance of hydrophobic and hydrophilic moieties in the amphiphiles is crucial for the formation of organized structures in aqueous solutions as evidenced by the formation of spherical and cylindrical micelles.

The organic molecules rotate across the single bonds leading to numerous temporary three-dimensional structures of varying energy known as conformers.
Alkynes to Aldehydes and Ketones: Hydroboration-Oxidation
One of the convenient methods for the preparation of aldehydes and ketones is via hydration of alkynes. Hydroboration-oxidation of alkynes is an indirect hydration reaction in which an alkyne is treated with borane followed by oxidation with alkaline peroxide to form an enol that rapidly converts into an aldehyde or a ketone. Terminal alkynes form aldehydes, whereas internal alkynes give ketones as the final product.
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,...

Preparation of Alcohols via Addition Reactions
The acid-catalyzed addition of water to the double bond of alkenes is a large-scale industrial method used to synthesize low-molecular-weight alcohols. An acidic atmosphere is required to allow the hydrogen in the water molecule to act as an electrophile and attack the double bond in an alkene. The addition of a proton to the double bond creates a carbocation intermediate. The proton preferentially bonds to the less substituted end of the double bond to create a more stable carbocation...
