Lindner, Ekkehard published the artcileStudies on steric and electronic effects on the reactivity of acetyl(diorganyl)-phosphines and their oxides, Name: Dimesitylphosphine oxide, the publication is Chemische Berichte (1980), 113(10), 3268-74, database is CAplus.
Acetylphosphines MeCOPRR1 (R = Ph, R1 = PhCH2, cyclohexyl, Me3C or R = R1 = m-CF3C6H4 or mesityl) were prepared by reaction of MeCOCl with Me3SiPRR1 or HPRR1 in the presence Et3N. Only acetyldimesitylphosphine is stable to mol. oxygen. The corresponding oxides MeCOP(O)RR1 (I) are formed by reaction of Ac2O with HP(O)RR1 and can be hydrolyzed with stoichiometric amounts of H2O to give AcOH and HP(O)RR1. I (R = Ph, R1 = PhCH2 or cyclohexyl, R = R1 = m-CF3C6H4) react further with HP(O)RR1 to give alcs. HOCMe[P(O)RR1]2. Steric and electronic effects of the R and R1 groups correlate with the reactivity of the prepared compounds
