Catalyticasymmetricsynthesis of secondary alkyl alcohols (up to 78% ee) was accomplished by asymmetric hydrogenation of enol diphenylphosphinates, derived from prochiral ketones such as acetophenone, 3-methyl-2-butanone, and 2-octanone, in the presence of a cationic rhodium complex of (R)-1-[(C)-1′,2-bis(diphenylphosphino)ferrocenyl]ethanol (BPPFOH).

Diphenylphosphinic acid adds across the triple bond of terminal alkynes in the presence of Ru3(CO)12, leading to regioselective formation of alkenyl diphenylphosphinates CH2=C(R)[OP(O)Ph2].
