Indirect reductive amination of aldehydes, catalyzed by polymer supported triphenylphosphine-palladium acetate complex PS-TPP-Pd(OAc)2 catalyst have been developed. The imine is prepared with molecular sieves in the first stage, followed by reduction with potassium formate catalyzed by PS-TPP-Pd(OAc)2. The recovered catalyst could be reused for four consecutive cycles without loss in activity a...

We use existing measurements of D − → K * 0 ρ − and B → ψ + K * , coupled with flavor independence of QCD, and with vector meson dominance to show that long distance contributions to B → ρ + γ are potentially very serious. We note that long distance (LD) contributions can be appreciably different in B − → ρ − + γ and B 0 → ρ 0 (ω) + γ. All radiative decays of B, B S are shown to be governed ess...

The current status of the experimental measurements and theoretical predictions of the anomalous magnetic moment of the muon aμ is briefly reviewed. The emphasis is put on the evaluation of the hadronic contribution to aμ as it has the largest uncertainty among all Standard Model contributions. The precision of the hadronic contribution is driven by the input e+e− data predominantly from the π+...

Octahedral molecular sieve (OMS) materials classified by their different tunnel sizes are defined edge-sharing MnO 6 octahedra. Four OMS (OMS-1, OMS-2, OMS-5, and OMS-6) benchmarked for ethane (C 2 H ) cyclohexane 12 oxidative dehydrogenation (ODH) compared with commercial , M1 phase MoVTeNb oxide, vanadium oxide (V O 5 ). The accessibility of the quadrilateral tunnels to C were further evaluat...

• ERI-type molecular sieves enhance ethylene selectivity in MTO . Acidity significantly influences ethylene-to-propylene ratio materials. Changes acidity alter hydrocarbon-pool species concentration and composition. Low acid site densities hinder the formation of aromatics (thus, ethylene) ERI. (SSZ-98, UZM-12, zeolite, SAPO-17) are synthesized with varying Si/Al = 5–9 Si/T-atoms 0.034–0.12 usi...

In this paper we study the implications of the recent high precision measurement of (g−2)μ by BNL [1] on new heavy physics beyond the SM. The effect of two d=6 operators on the anomalous magnetic momment of the muon is considered and the new physics contribution to aμ reported by BNL has been used to put bounds on the scale associated with these operators.

We have performed a search for the angular-momentum forbidden decay K+→π+γ with the E787 detector at BNL. No events were observed in the π+ kinematic region around 227 MeV/c. An upper limit on the branching ratio for the decay is set to be 3.6× 10−7 at 90% confidence level. Typeset using REVTEX
