Three-Component Reaction between Vinyl Ethers, Secondary Phosphines, and Elemental Selenium: One-Pot Synthesis of 1-(Alkoxy)ethyl and 1-(Aryloxy)ethyl Phosphinodiselenoates
aryl, etc.), were synthesized by means of a three-component reactionbetween the elemental selenium and the corresponding vinyl ether and secondary phosphine. The reaction proceeds readily in 1,4-dioxane at 90 ˚C for 1-1.5 hours and gives the phosphinodiselenoic esters quantitatively and in an entirely atom-economic manner. The reaction proceeds through electrophilic addition to the electron-rich

Thioselenophosphinic acids, R2P(Se)SH, generated in situ from secondaryphosphinesulfides and elemental selenium, easily add to various vinyl ethers (equimolar ratio, 100 °C, 1,4-dioxane, up to 40 min) to give earlier unknown S- and Se-[1-(organyloxy)ethyl]thioselenophosphinates, i.e., R2P(Se)SCH(Me)OR′ and R2P(S)SeCH(Me)OR′ (R, R′=alkyl, aralkyl, hetaralkyl and aryl), the S-esters being predominant

Polyfluoroalkyl vinyl ethers take up aliphatic and aromatic carboxylic acids in the presence of 0.2-5 wt% of trifluoroacetic acid at 55-105degreesC to give fluorine-containing hemiacetals in 60-100% yields.
