General description

Co-catalyzed reaction between cyclopentene and 1-phenyl-1-propyne has been reported. Bonding properties of 1-phenyl-1-propyne on Cu(111) at 100K have been studied using temperature-programmed desorption and X-ray, ultraviolet and two-photon photoemission spectroscopies. 1-Phenyl-1-propyne is an inhibitor of dopamine beta-hydroxylase. Polymerization of 1-phenyl-1-propyne by TaCl5 and NbCl5 has been reported.

1-Phenyl-1-propyne serves as a starting material for various chemical reactions, such as addition reactions and polymerization.

The catalytic action of dopamine beta-hydroxylase on 1-phenyl-1-propyne results in concomitant loss of enzyme activity. At pH 5.5 and 25 degrees C, 1-phenyl-1-propyne inactivates dopamine beta-hydroxylase in a mechanism-based fashion. The inactivation rate is first-order, follows saturation kinetics, and is

Here we report a general method for the measurement of (13)C kinetic isotope effects at natural abundance for reactions that yield two or more products concurrently. We use, as an example, a recently reported Co-catalyzed reaction between cyclopentene and 1-phenyl-1-propyne.

The bonding properties of 1-phenyl-1-propyne (PP, C6H5CCCH3) on Cu(111) at 100 K have been studied using temperature-programmed desorption (TPD), and X-ray, ultraviolet, and two-photon photoemission spectroscopies (XPS, UPS, and 2PPE). In TPD, there is no evidence for dissociation. Multilayer desorption
