Through the article, more information about this compound (cas:97739-46-3) is conveyed.

Extrapolated elec. breakdown field strengths of hexane vapor to pressure giving d. corresponding to the liquid state are higher than those actually observed for the liquid. Above the critical temperature, the observed breakdown strengths are less than the extrapolated curve for d. more than 0.01 g./cc., probably due to field emission. The breakdown strengths of the liquid are significantly lower than those of the vapor, but new measurements show that the values converge as one approaches the critical point. The observations suggest that the lower strengths in the liquid result from formation of vapor bubbles (CA 54, 18131b).

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Highly ligand-controlled regioselective Pd-catalyzed aminocarbonylation of styrenes with aminophenols, published in 2016-05-25, which mentions a compound: 97739-46-3, mainly applied to phenyl amide regioselective synthesis ligand controlled; styrene regioselective aminocarbonylation aminophenol palladium catalyst phosphine phosphaadamantane; aminocarbonylation reaction mechanism boronic acid chlorosalicylic additive, Quality Control of 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane.

Achieving chemo- and regioselectivity simultaneously is challenging in organic synthesis. Transition metal-catalyzed reactions are effective in addressing this problem by the diverse ligand effect on the catalyst center. Ligand-controlled regioselective Pd-catalyzed carbonylation of styrenes with aminophenols was realized, chemoselectively affording amides. Using a combination of boronic acid and 5-chlorosalicylic acid as the additives, linear amides were obtained in high yields and selectivity using tris(4-methoxyphenyl)phosphine in acetonitrile, while branched amides were obtained in high yields and selectivity in butanone by changing the ligand to 1,3,5,7-tetramethyl-2,4,8-trioxa-6-phenyl-6-phosphaadamantane. Further studies show that the nature of the ligand is key to the regioselectivity. Cone angle and Tolman electronic parameter (TEP) have been correlated to the reactivity and regioselectivity. Studies on the acid additives show that different acids act as the proton source and the corresponding counterion can help enhance the reactivity and selectivity.
