- W2108183105 abstract "The substituent effect on the rate of reaction of trimethyl phosphite with aliphatic α-diketones has been studied in anhydrous dioxan by UV spectrophotometry. The rate constant (k) in the rate equation, v = k[(MeO)3P] [RCOCOR′], decreases with change of R and R′ in the order methyl, ethyl, n-propyl, n-butyl, iso-propyl, iso-butyl and sec-butyl. Practically no reaction was observed with t-BuCOCOBu-t at room temperature. The reaction of (MeO)3P with RCOCOR fits the Taft equation, log(k/ko) = +1·08Es, + 0·012, which shows the predominance of steric effect, while the reaction of (MeO)3P with MeCOCOR′ fits the equation, log(k/ko) = + 1·17σ* + 0·001, which shows the superiority of polar effect. These results are discussed in terms of previous mechanism involving a nucleophilic attack of phosphorus on a carbonyl carbon of an α-diketone, and may exclude an one-electron transfer mechanism." @default.
