Multicolor chemiluminescent acridinium derivatives were synthesized by attaching various common fluorophores to the N10 -acridinium position through a piperazine linker. Triggering of each acridinium derivative using alkaline hydrogen peroxide result

Two synthetic strategies are investigated for the preparation of water-soluble iridium-based catalysts for NMR signal amplification by reversible exchange (SABRE). In one approach, PEGylation of a variant N-heterocyclic carbene provided a novel catal

Heterobifunctional compounds are of considerable interest in convergent synthesis strategies as well as in the labeling/tagging of biological molecules. Herein is described a synthetic strategy to functionalize sulfonic acids in the presence of carbo
