Grayson, J. Ian published the artcile[(Phenylthio)allyl]- and [(phenylthio)vinyl]phosphine oxides. Synthesis of 1-(phenylthio)butadienes and a three-component synthesis of ketones, Synthetic Route of 4141-48-4, the publication is Journal of the Chemical Society, Perkin Transactions 1: Organic and Bio-Organic Chemistry (1972-1999) (1987), 967-76, database is CAplus.
The functionalization of some substituted allyl- and vinyldiphenylphosphine oxides is explored and routes to substituted ¦Ã-phenylthioallyl- and ¦Ã-phenylthiovinylphosphine oxides are described. These reagents are used in the synthesis of the title compounds Thus, reaction of Ph2P(O)CHMeSPh (I) with Ac2O for 8 days under acidic conditions gives 65% Ph2P(O)C(SPh):CH2 (II). I also forms 66% II by direct chlorination with N-chlorosuccinimide in CCl4 and subsequent HCl elimination on silica. Treatment of II with RLi (R = Me, Bu, Me2CHCH2) followed with NH4Cl-H2O affords Ph2P(O)CH(CH2R)SPh. Addition of MeLi to II followed with PhCHO gives PhSC(CH2Me):CHPh, which is hydrolyzed to give MeCH2COCH2Ph. The deprotonation and subsequent alkylation or thiolation reactions are presented for a variety of alkenyldiphenylphosphine oxides.
