The polymorphism of porphyrin 2D assemblies at the liquid-graphite interface: The effect of a polar solvent additive and a flexible spacer on the face-on and edge-on type molecular arrangements

, p. 8836 - 8839 (2019)
Self-assembly structures of 5,10,15,20-tetrakis(4-substituted phenyl)porphyrins at the liquid-graphite interface were investigated by scanning tunneling microscopy. We found that the presence of a small amount of a polar solvent, i.e., only 0.5 vol% of octanoic acid in phenyloctane, significantly affected the selective formation of the face-on polymorph over the edge-on one likely due to the solvent-molecule interactions at the 2D interface.

The oxidation of alcohols to aldehydes using stoichiometric 4-acetamido-2,2,6,6-tetramethylpiperidine-1-oxoammonium tetrafluoroborate (1) in CH2Cl2 at room temperature is a highly selective process favoring reaction at the carbinol center best able to accommodate a positive charge. The oxidation of aldehydes to carboxylic acids by 1 in wet acetonitrile is also selective; the rate of the process correlates with the concentration of aldehyde hydrate. A convenient and high yield method for oxidation of alcohols directly to carboxylic acids has been developed.
Chemoselective conversion of α-unbranched aldehydes to amides, esters, and carboxylic acids by NHC-catalysis
Kuwano, Satoru,Harada, Shingo,Oriez, Raphael,Yamada, Ken-Ichi
supporting information; experimental part, p. 145 - 147 (2012/01/12)
Depending on the N-heterocyclic carbene catalyst utilized, α-unbranched aldehydes selectively provided amides, esters, or carboxylic acids through oxidation by NCS. The α-unbranched aldehyde underwent these reactions chemoselectively in the presence of an aromatic or α-branched aldehyde.

Rhodium(I)-catalyzed 1,4-addition of arylboronic acids to acrylic acid in water: One-step preparation of 3-arylpropionic acids
Vautravers, Nicolas R.,Breit, Bernhard
supporting information; experimental part, p. 2517 - 2520 (2011/11/12)
A practical method for the one-step preparation of 3-arylpropionic acids through rhodium-catalyzed 1,4-addition of arylboronic acids to acrylic acid is reported. The method is applicable to a broad scope of aryl boronic acids and displays a wide functional group tolerance operating in water as the optimal reaction medium.
