Paragraph 0021; 0023; 0025, (2017/08/29)
The invention discloses a method of synthesizing 4-decenoic acid, including the following steps: performing heat reflux with 1-octylene-3-ol and ortho-acetate as raw materials in presence of a catalyst, distilling generated ethanol out at the same time, performing reduced pressure distillation to remove excessive ortho-acetate, and finally rectifying the product to obtain pure 4-decenoate; performing heat reflux to the 4-decenoate under an alkaline condition and distilling hydrolyzed alcohol compounds out, regulating the pH to 7, extracting and distilling the liquid, and finally rectifying the liquid to obtain pure 4-decenoic acid. The pure 4-decenoic acid is prepared through a Claisen rearrangement reaction. The synthesis process is simple.

Oxime benzoates and O-benzoyl hydroxamic acid derivatives react with tributylstannane in the presence of AIBN to give iminyl, amidyl, and carbamyl radicals which can be captured by an internal olefin.
Selectivity of Radical Formation in the Reaction of Carbonyl Compounds with Manganese(III) Acetate

The selectivity of radical generation in the oxidation of carbonyl compounds by manganese(III) has been studied in two ways.Competitive reaction of acetic and propionic acids under conditions in which the resultant radicals are trapped efficiently by an alkene suggests that propionic acid reacts some 3.8 times more readily than does acetic acid.Oxidation of butanone under similar conditions gives products in the formation of which reaction has occurred 2.9 times more readily at C-3 of butanone than at C-1.However, this ratio reflects a combination of chain propagation and of initiation by manganese(III) oxidation.When propagation is effectively eliminated, the C-1 position is the more reactive.The significance of these observations on the mechanism of oxidation of carbonyl compounds by manganese(III) is discussed.It is suggested that enol radical-cations can be formed in the reaction but that these do not give carbonyl-stabilised radicals by deprotonation.
