A fluorescent probe for a lewisite simulant

A fluorescent probe showed high selectivity and sensitivity for an organoarsenic blister agent simulant, arsenic trichloride.

Functionalised 1-Alkynylarsines: Synthesis, Characterisation, and Attempts of Rearrangement into Functionalised Arsaalkynes

Functionalised 1-alkynylarsines were synthesised by reaction of the corresponding 1-alkynyltributylstannane on arsenic trichloride followed by chemoselective reduction of the formed 1-alkynyldichloroarsine by tributyltin hydride in the presence of small amounts of a radical inhibitor. Rearrangements of these compounds into the corresponding arsaalkynes were attempted.
