Nanomolar Detection of Palladium (II) through a Novel Seleno-Rhodamine-based fluorescent and colorimetric chemosensor

A novel reversible fluorescent probe for Pd2+ based on a rhodamine-containing selenide (Rh–Se) was designed, synthesized and fully characterized. The probe Rh–Se showed a high selectivity and sensitivity with a detection limit of 32 nM for Pd2+ ions. The formation of a complex Rh–Se/Pd2+ was confirmed by HRMS. DFT calculations revealed that the proposed square planar geometry is the most stable form of the metallic complex Rh–Se/Pd2+. The probe Rh–Se showed to have high potential for the detection of residual Pd2+ in synthetic cross-coupling products and simulated pharmaceutical Pd2+- contaminated products.

Method for preparing iodo-benzoic acid (ester) by improving moral Michael reaction

The invention discloses a method for preparing iodo-benzoic acid (ester) by improving a moral reaction, and belongs to the technical field of organic synthesis. The method comprises the following steps: preparing and separating the diazonium tetrafluoroborate through diazotization of aminobenzoic acid (ester) and then performing iodination reaction with the iodinated reagent in an organic medium to obtain the corresponding iodo carboxylic acid (ester). The iodo-benzoic acid (ester) prepared by the method has high purity. The method has the advantages of good quality and simple post-treatment, and the product yield reaches 70 - 90%.

Preparation of N-Arylquinazolinium Salts via a Cascade Approach

An easy manipulation method for the preparation of N-arylquinazolinium salts is described from readily available aryldiazonium salts, nitriles, and 2-aminoarylketones in a one-pot operation. This method relies on the in situ generation of the N-arylnitrilium intermediate from the reaction of aryldiazonium salt with nitrile, which undergoes amination/cascade cyclization/aromatization, leading to N-arylquinazolinium salts in excellent yields. Nucleophilic addition of alkoxide to these N-arylquinazolinium salts provides functionalized dihydro-N-arylquinazoline.
