Highly selective synthesis of [(Z)-3-chloro-2-(phenylselanyl)-1-alkenyl] phosphonates and 2-ethoxy-4-(phenylselanyl)-2,5-dihydro-1,2-oxaphosphole 2-oxides by electrophilic reaction of 1,2-alkadienylphosphonates with PhSeCl

The reactions of monosubstituted 1,2-alkadienylphosphonates with PhSeCl in THF or dioxane/H2O (10:1) at 70 °C afforded the selenochlorination products [(Z)-3-chloro-2-(phenylselanyl)-1-alkenyl] phosphonates with very high chemo-and stereoselect

The reactivity of dialkyl esters of 1, 2-alkadienephosphonic acids towards sulfenyl-and selenenyl-bromides was investigated. The reactions of 3,5 with phenylsulfenyl and phenylselenenyl-bromides were performed in polar solvent at low temperature and argon
Sulfur- and Selenium- Promoted Cyclization of Allenic Phosphonates and Phosphinates to Substituted 1,2-Oxaphosphol-3-enes; Stereochemical Consequences at Phosphorus. The Crystal and Molecular Structure of (Z)-3,5-Di-tert-butyl-2-methoxy-4-(phenylseleno)-1,2-oxaphosphol-3-ene 2-Oxide

A series of allenic phosphonate esters (4a-d) and phosphinate 6 were reacted with benzeneselenyl chloride.Except for 4a, which gave a simple 1,2-adduct, each ester afforded the corresponding 4-(phenylseleno)-1,2-oxaphosphol-3-ene (11b-e).Similar reaction of the esters with 2,4-dinitrobenzenesulfenyl chloride gave the corresponding 4-thio derivatives (13) in cases 4c, 4d and 6; 4a and 4b were unreactive.The diastereomers of 11b were seperated, and the structure of the Z isomer was established by X-ray crystallography.The stereochemistry of the cyclization and related reactions is discussed.
