Khachatryan, R. H. published the artcilePhase-transfer catalysis in synthesis of unsaturated phosphine oxides, SDS of cas: 4141-48-4, the publication is Khimicheskii Zhurnal Armenii (1999), 52(1-2), 77-84, database is CAplus.
Unsaturated tertiary phosphine oxides were prepared in 51-93% yields by reaction of R2P(O)H (R = Ph, Et) with alkenyl or alkynyl halides, e.g., CH2:CHCH2Br, ClCH2CH:CMe2, ClCH2CH:C(Me)Cl, ClCH2Cú·CMe, ClCH2Cú·CH, ClCH2CH:CH2, in C6H6 containing a catalytic amount of Katamine AB and excess KOH or K2CO3. The nature of the base affects the structure of the products obtained. Effective methods for synthesis of tertiary phosphine oxides with 1- and 2-propenyl, substituted 2-propenyl, 1,2-propadienyl, 1-propynyl and 2-butynyl groups were worked out. A higher tendency for isomerization of diphenyl-2-propynyl-phosphine oxide as compared with the di-Et analog was observed Use of phase-transfer catalysis for synthesis of unsaturated tertiary phosphine oxides is preferable to a superbasic medium.
