General Synthetic Method for Si-Fluoresceins and Si-Rhodamines

ACS Central Science, 2017
The century-old fluoresceins and rhodamines persist as flexible scaffolds for fluorescent and fluorogenic compounds. Extensive exploration of these xanthene dyes has yielded general structure–activity relationships where the development of new probes is ...

Synthesis of Thioxanthone 10,10-Dioxides and Sulfone-Fluoresceins via Pd-Catalyzed Sulfonylative Homocoupling. [PDF]

Org Lett
Our report describes the facile and scalable preparation of 9H-thioxanthen-9-one 10,10-dioxides via Pd-catalyzed sulfonylative homocoupling of the appropriately substituted benzophenones. This transformation provides a straightforward route to previously

Increased ammonification, nitrogenase, soil respiration and microbial biomass N in the rhizosphere of rice plants inoculated with rhizobacteria

Journal of Integrative Agriculture, 2021
Azospirillum brasilense and Pseudomonas fluoresceins are well-known plant growth promoting rhizobacteria. However, the effects of A. brasilense and P. fluoresceins on the N cycles in the paddy field and rice plant growth are little known.

Synthesis of Rhodamines from Fluoresceins Using Pd-Catalyzed C–N Cross-Coupling

Organic Letters, 2011
A unified, convenient, and efficient strategy for the preparation of rhodamines and N,N′-diacylated rhodamines has been developed. Fluorescein ditriflates were found to undergo palladium-catalyzed C–N cross-coupling with amines, amides, carbamates, and ...

Selective Hg(II) detection in aqueous solution with thiol derivatized fluoresceins.

Inorganic Chemistry, 2006
The syntheses and photophysical properties of mercury sensors 2 and 3 (MS2 and MS3), two asymmetrically derivatized fluorescein-based dyes designed for Hg(II) detection, are described. These sensors each contain a single pyridyl-amine-thiol metal-binding
