Abstract
But-2-yne-1,4-diylbis(triphenylphosphonium) diiodide reacts with 2-sulfanylethan-1-ol in the presence of triethylamine to form a 1 : 1 adduct. Under similar conditions, ethane-, butane- and 2-methylbutane- 1-thiols form [4-(alkylsulfanyl)buta-1,3-dien-1-yl]triphenylphosphonium iodides, probably via β-cleavage of the original salt involving vinylethynyl intermediate. Features of the reaction of but-2-ynebisphosphonium salt with 3,5-dimethylpyrazole, hydrazine and its derivatives have been studied.
