Abstract:
The development of a novel and stable functional material for photocatalytic organic transformation and proton conduction is of great research significance in the manufacture of crucial drug intermediates and proton-exchange membrane fuel cells. In this study, we employed Na2MoO4, NaAsO2, and RhCl3 to construct a Rh-containing arsenomolybdate Na16(H3O)4[H2N(CH3)2]2[As12Mo31O129Rh4(OH)2(H2O)]·27H2O (1). The detailed crystallographic analysis determined that compound 1 has a symmetrical structure consisting of two identical {As6Mo15Rh2} clusters bridged by a MoVI center through Rh and As from each {As6Mo15Rh2} group, which was further comprehensively characterized by common spectroscopic methods, encompassing X-ray photoelectron spectroscopy, powder X-ray diffraction, thermogravimetric analysis, and elemental analysis. The systematic impedance spectroscopy revealed that compound 1 not only displays excellent proton conductivity but also retains structural integrity after exposure to different temperature and humidity conditions. Additionally, the high activity and robustness of compound 1 in the photosynthetic aniline were verified after 6 h of visible-light irradiation in a N2 environment.

Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
Rate-Determining Steps
In a multistep reaction mechanism, one of the elementary steps progresses significantly slower than the others. This slowest step is called the rate-limiting step (or rate-determining step). A reaction cannot proceed faster than its slowest step, and hence, the rate-determining step limits the overall reaction rate.
The concept of rate-determining step can be understood from the analogy of a 4-lane freeway with a short-stretch of traffic-bottleneck caused due to...
