Characterization of water/sucrose laurate/n-propanol/ allylbenzene microemulsions

Water/n-propanol/sucrose laurate/allylbenzene micellar systems were formulated and applied in the isomerization of allylbenzene in the presence of heterogenized derivatives of some platinum group catalysts. The ratio (w/w) of n-propanol/surfactant studied herewith was 2/1. Temperature insensitive microemulsions were found. The microemulsions were characterized by the volumetric parameters, density, excess volume, ultrasonic velocity, and isentropic compressibility. The densities increase with increases in the water volume fraction. Excess volumes of the microemulsions decrease for water volume fractions below 0.2, level off for water volume fractions between 0.2 and 0.6 then increase for water volume fractions above 0.6. Excess volumes of the studied micellar systems increase with temperature. Isentropic compressibilities increase with temperature for water volume fractions below 0.8 and decrease for water volume fractions above 0.8. Structural transitions from water-in-oil to bicontinuous to oil-in-water occur along the microemulsion phase. The particle hydrodynamic diameter of the oil-in-water microemulsions at the 0.95 water volume fraction was found to decrease with temperature. AOCS 2012.

The Autocatalytic Isomerization of Allylbenzene by Nickel(0) Tetrakis(triethylphosphite)

Using [Ni{(POEt)3}4] as catalyst precursor for the catalytic isomerization of allylbenzene to beta-methylstyrene, time-course studies suggest a mechanism that is consistent with an autocatalytic reaction. The sigmoidal curve observed when plotting conversion vs. time fits exceptionally well to a kinetic model of an autocatalytic process (R2 = 0.998). We show that the uncoordinated phosphite, generated during the catalyst activation, reduces the acid concentration and, consequently, has a detrimental effect on the formation of the protonated active nickel catalyst. The nickel complex protonation is seen as a key step in forming the active catalytic species. The novel use of a mercury salt as a phosphite scavenger leads to inhibition of the free phosphite's capability to lower acid concentration, improving the catalytic performance of the system, consistent with the mechanism proposed.

Small molecule activation by mixed methyl/methylidene rare earth metal complexes

Diverse reactivity patterns of mixed tetramethyl/methylidene rare-earth complexes bearing bulky benzamidinate coligands L3Ln3(μ2-Me)3(μ3-Me)(μ3-CH2) [L = [PhC(NC6H3iPr2-2,6)2]-; Ln = Y(1a), Lu(1b)] with PhCN, alkynes, and CS2 have been established. Reaction of complexes 1 with PhCN gave the μ3-CH2 addition complexes (NCNdipp)3Lu3(μ2-Me)3(μ3-Me)[μ-η1:η1:η3-CH2C(Ph)N] [Ln = Y(2a), Lu(2b)]. Treatment of complexes 1 with phenylacetylene afforded unexpected alkenyl dianion complexes L3Ln3(μ2-Me)3(μ3-Me)(μ-η1:η3-PhC≡CMe) [Ln = Y(3a), Lu(3b)] through the insertion of rare earth methylidene into a C-H bond in a reductive fashion. However, reaction of complexes 1 and HC≡CSiMe3 gave μ3-Me protonolysis complexes L3Ln3(μ2-Me)3(μ3-C≡CSiMe3)(μ3-CH2) [Ln = Y (4a), Lu (4b)] in excellent yields. Treatment of complexes 1 with CS2 led to the formation of the methyl activation complexes L3Ln3(μ2-Me)2(μ3-CH2)(μ3-η1:η2:η2-S2C≡CH2) [Ln = Y(5a), Lu(5b)]. All the new complexes were fully characterized.

Observation of intermediates in Wittig reactions of non-stabilized phosphonium ylides bearing a phosphaheteratriptycene skeleton containing Group 15 elements with benzaldehyde

The heteroatom effect of Group 15 elements (P, As, Sb and Bi) has been investigated on stereochemical drift in the Wittig reactions of non-stabilized phosphonium ylides bearing a phosphaheteratriptycene skeleton with benzaldehyde. 1,2-Oxaphosphetanes were observed as intermediates and the isomerization from cis-form to trans-form, the origin of stereochemical drift, was detected between ?90 °C and 25 °C by VT-31P{1H} NMR spectroscopy. The isomerization was found to start at lower temperatures as the raw number of heavier period elements. Cross experiments showed that the isomerization occurred through equilibrium between 1,2-oxaphosphetanes and phosphonium ylides-benzaldehyde.GRAPHICAL ABSTRACT (Figure presented.).

Wittig reactions of non-stabilized phosphonium ylides bearing a phosphaheteratriptycene skeleton containing group 14 and 15 elements with benzaldehyde

Wittig reactions of non-stabilized phosphonium ylides bearing a phosphaheteratriptycene skeleton containing Group 14 and 15 elements (PhSi, PhGe, PhSn, n-BuSn, P, As, Sb, and Bi) at another bridgehead position with benzaldehyde provided (Z)-olefins as a major product in the cases of period 3 elements (PhSi, P) and (E)-olefins as a major product in the cases of below period 4 elements (PhGe, PhSn, n-BuSn, As, Sb, and Bi). These results are attributed to stereochemical drift of the intermediates come from the heteroatom effect at another bridgehead position of the phosphaheteratriptycene skeleton.
