Reactions of tetracyclic tetraaminophosphoranes with dichloroperfluoro cyclic and acyclic alkenes and halo compounds

Cyclenphosphorane was reacted with 1,2-dichlorotetrafluorocyclobutene- 1, 1 ,2-dichlorohexafluorocyclopentene- 1, 1,2-dichlorooctafluorocyclohexene-1 i odopentafluorobenzene, 2-iodo-1,1,1-trifluoroethane, and,2,3-dichlorohexafl uorobutene-2 in the presence of triethylamine at room temperature in tetrah ydrofuran to form monochlorotetrafluorocyclobutenylcyclenphosphorane monoch lorohexafluorocyclopentenylcyclenphosphorane, monochlorooctafluorocyclohexe nylcyclenphosphorane, pentafluorophenylcyclenphosphorane, 1,1,1-trifluoroet hylcyclenphosphorane, and 2-chlorohexafluorobut-2-enylcyclenphosphorane in 70-80% yields, respectively. Cyclamphosphine oxide reacted with dichloroper fluorocyclic alkenes in the presence of triethylamine in chloroform to form N-(chlorotetrafluorocyclobutenyl)cyclamphosphine oxide, N-(chlorohexafluor ocyclo-pentyl)cyclamphosphine oxide and N-(chlorooctafluorocyclohexenyl)cyc lamphosphine oxide in similar to 50% yields, respectively. These moisture s ensitive cyclamphosphine oxide derivatives are stable and are soluble in CH Cl3, CH3CN and DMSO. (C) 1998 Elsevier Science S.A. All rights reserved.
