Synthetic studies on prostaglandins: "synthesis of a new thia-PGEI analog"
… to ethynyl n.pentyl sulfide 81 is via a double dehydrohalogenation of the corresponding 1,2-dibromoethyl sulfide with sodium amide in liquid ammonia. In addition, the isomerically pure E-2-iodoethenyl n.pentyl sulfide 85 is conveniently prepared in high yield and stereoselectivity by …

Synthetic approaches to new three coordinate Group 6 compounds : chromium alkenyls, molybdenum thiolates and tungsten amides
… ligands are synthesized by bromination and dehydrohalogenation of an adamantyl olefin to yield an alkenyl bromide. The Grignard reagent, derived from the bromide, is used either as a transmetallation reagent, or reacted with elemental sulfur to form a magnesium thiolate, (THF)2Mg(SC[Ad]Ar)2. …

Synthesis and reactivity of some β-substituted alkylphosphonates
… have been achieved, since once again the dehydrohalogenation product predominates. During an attempted synthesis of diethyl 2-iodopentylphosphonate by reaction of diethyl 2-chloropentylphosphonate with NaI, an unusual interaction between the sodium cation and the substrate in acetone …

Synthesis and Reactivity of Phosphorus-Containing Heterocycles and Tetrahedranes
… (ᵗBuC)₃P was prepared via the dehydrohalogenation of fluorophosphine (ᵗBuC)₃P(F)H. The phosphatetrahedrane core was confirmed spectroscopically and by X-ray diffraction analysis. Hydrogen-hydrogen bonding interactions between neighboring tert-butyl groups of (ᵗBuC)₃P were …
