Molecular structure of butanediol isomers in gas and liquid states: Combination of DFT calculations and infrared spectroscopy studies

Density functional theory (Becke3LYP/6-311++G**) conformational analysis was carried out for all positional butanediol isomers. Taking into account the relative populations of the most stable conformers at 298.15 K, the weighted mean enthalpies of each butanediol isomer in the gas state were computed. Combining these results with the experimental values for the enthalpies of vaporization at 298.15 K, an estimate of the enthalpy of each of the butanediol isomers in the liquid state was obtained and discussed. The insight into the structural changes at the molecular level from the isolated molecule to the condensed state was improved by an infrared spectroscopy study in the OH stretching region, which was carried out for a wide range of concentrations of carbon tetrachloride solutions and pure liquids. The spectroscopic studies essentially confirmed the results derived from the combination of the computational and calorimetric studies.

Homochiral arsenic-/phosphorus-based ligands

The synthesis of homochiral phosphorus-based ligands has escalated dramatically over the last decade in the drive to develop new, and further fine tune existing, base structures of chiral auxiliaries that have had, and most certainly are continuing to have, a phenomenal impact in the arena of enantioselective catalysis. This review highlights the vast array of homochiral phosphorus-based ligands and their significantly fewer arsenic-based analogs, the key synthetic strategies used to prepare them and the significant roles that they have been employed in after coordination to a transition metal center.

A new sulfenylation reagent, 3-phenylsulfenyl-2-(N- cyanoimino)thiazolidine, and its optically active version

We have developed a new sulfenylation reagent, 3-phenylsulfenyl-2-(N- cyanoimino)thiazolidine 3, that is readily available and stable upon storage. Compound 3 easily reacts with amines or thiols to give the corresponding sulfenamides or asymmetrical disulfides in excellent yields. It was also found that the alpha-sulfenylation reaction of carbonyl compounds with 3 proceeds smoothly. Furthermore, optically active 4-diphenylmethyl derivative 4 was synthesized as an asymmetric sulfenylation reagent, which realized 96% e.e. upon alpha-sulfenylation of a cyclic beta-keto ester.
