Ultraviolet Photodissociation Dynamics of the 1-Propenyl Radical.
Ultraviolet (UV) photodissociation dynamics of jet-cooled 1-propenyl radical (CHCHCH3) were investigated at the photolysis wavelengths from 224 to 248 nm using high-n Rydberg atom time-of-flight (HRTOF) technique. The 1-propenyl radicals were produced from 193 nm photolysis of 1-chloropropene and 1-bromopropene precursors. The photofragment yield (PFY) spectra of the H atom product have a broad...
متن کاملCrystal structure of 2-Se-(2-methyl-2-propenyl)-1-benzoic acid.
C11H12O2Se is triclinic, P1. Unit-cell dimensions at 293 K are a = 5.8450(10), b = 8.1490(10), c = 11.4620(10)A, alpha = 97.050(10), beta = 90.140(10), gamma = 90.120(10) degrees, V = 541.81(12)A3, Dx = 1.564 g/cm3, and Z = 2. The R value is 0.047 for 1388 observed reflections. The dihedral angle between the phenyl ring and the isobutenyl group is 72.3(2) degrees. There is an intermolecular hyd...
متن کاملSelective route to 2-propenyl aryls directly from wood by a tandem organosolv and palladium-catalysed transfer hydrogenolysis.
A tandem organosolv pulping and Pd-catalysed transfer hydrogenolysis depolymerisation and deoxygenation has been developed. The tandem process generated 2-methoxy-4-(prop-1-enyl)phenol in 23% yield (92% theoretical monomer yield) starting from pine wood and 2,6-dimethoxy-4-(prop-1-enyl)phenol in 49% yield (92% theoretical monomer yield) starting from birch wood. Only endogenous hydrogen from wo...
متن کاملRotational propensities and identity of bond rupture in 1-cyano-2-methyl-3-(cis-propenyl) cyclopropanes.
Comparison of the rate of recemization with the rates of diastereomerization in the title compound allows the firm conclusion to be drawn that the theoretically weakest of the three cyclopropane bonds is preferentially broken irrespective of the multiplicity of the internal rotations involved. Incidentally, the effect of an adjacent chiral methyl group on internal rotational propensities is elu...
متن کاملEffect of N-(3-phenyl-2-propenyl)-1-deoxynojirimycin on the lectin binding to HIV-1 glycoproteins.
The effect of N-(3-phenyl-2-propenyl)-1-deoxynojirimycin (ppDNM) on the lectin binding to HIV-1 glycoprotein was analyzed by using biotinylated lectins of various sugar specificities as probes. ppDNM potentially inhibited HIV-1-induced syncytium formation and viral infectivity of HIV-1 without cytotoxicity. The lectin binding assay showed that ppDNM treatment reduced Con A binding to gp120 of H...
