Enchev, Dobromir D.
, p. 156 - 158 (2007/10/03)
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

The reaction of cyclohexylideneethenylphosphonic acid and its esters with arylselenenyl chlorides leads to the formation of 4-arylseleno-2-oxo-1-oxa-2-phospha-spiro(4,5)-3-decene derivatives.The dichloride of this acid with the same reagent cyclized only

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.
