In this work, FeNi layered double hydroxides/graphene oxide (FeNi LDH/GO) was prepared, which exhibits excellent selective cataluminescent performance towards propylene oxide. The selectivity and sensitivity of the cataluminescence (CTL) reaction were investigated in detail. Moreover, the catalytic reaction mechanism, including the intermediate products and the conversion of reactants to products, was discussed based on both the experimental and computational results. Furthermore, the proposed FeNi LDH/GO based CTL sensor was successfully applied for the determination of propylene oxide residue in fumigated raisins, which indicates extensive application potential for rapid food safety evaluation.

Vapor-phase catalytic dehydration of 1,2-propanediol was investigated over several solid acid catalysts, such as alumina, silicaalumina, HY zeolite, and α-zeolite. These acids catalyzed the dehydration of 1,2-propanediol to produce propanal (Figure 1), while zeolites were particularly deactivated because of deposition of carbonaceous species. An amorphous silicaalumina was modified with metals such as Ag and Cu to stabilize the catalytic activity under hydrogen flow conditions. Ag-modified silicaalumina is a promising catalyst for the production of propanal from 1,2-propanediol.

The formation of 1,4-dioxanes and alkyl chlorides from the reactions of polyethers (dme, diglyme, 1,2-diethoxyethane, 1,2-dimethoxypropane) with NbCl5 at room temperature is described; as far as dme is concerned, the reaction mainly occurs in two steps, consisting of (i) cleavage of one O-CH3 bond, followed by (ii) cleavage of the second O-CH3 bond and one of the two O-CH2 linkages. The characterization of intermediate complexes and the isolation of NbOCl3(dme) are reported. The Royal Society of Chemistry.
OLIGOMERISATION OF METHYLOXIRANE INITIATED BY (C6H5)3C(1+)AsF6(1-), (C6H5)3C(1+)SbCl6(1-) AND SbCl5

Reactions of methyloxirane with the titled compounds lead to the formation of a mixture of cyclic and linear oligomers with average polymerisation degree ranging from 5 to 10.The oligomers are formed by combination of back-bitting reaction with re-initiation of the transiently desactivated reaction centres followed by monomer transfer.The important role which these reactions play in the overall oligomerisation of methyloxirane is due to the fact that in addition to active centres with the structure of oxonium ions, also carbenium active centres participate significantly in the reaction.In the systems with stable pair anions AsF6(1-), the irreversible termination of active centres does not take place, in contrast to the latter systems.This termination involves the reaction of the cation of active centre with the pair anion which releases one ligand during this interaction.The results obtained indicate that in the systems initiated by SbCl5 the active centres of amphiion structure can play an important role in the initial stages of the reaction.
