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%.

Additions to N-Sulfinylamines as an Approach for the Metal-free Synthesis of Sulfonimidamides: O-Benzotriazolyl Sulfonimidates as Activated Intermediates

Sulfonimidamides are obtained in moderate to very good yields from the key intermediates O-benzotriazolyl sulfonimidates, which are formed by reacting aryldiazonium tetrafluoroborates, N-tritylsulfinylamine, and N-hydroxybenzotriazole hydrate in a process mediated by a tertiary amine. The formation of the sulfonimidate proceeds in inexpensive and environmentally benign dimethyl carbonate as the solvent, it does not require anhydrous conditions, and the product yields generally exceed 70 %. The substrate scope is broad, and a wide range of sensitive organic functionalities is well tolerated. The reactions probably proceed via aryl radicals formed from diazonium cations with assistance from both the tertiary amine and the sulfinylamine.
