Embodiment 101
[0238] With 0.442g (1.00mmol) three (2,6-dimethoxyphenyl) phosphine (hereinafter referred to as "2,6-DMPP") and 14.3g (105mmol) phenyl acetate (in formula (2) R 1 is methyl, OZ 1 Carboxylate of an organic group formed by phenol) was put into a 100ml flask, and after heating up to 90°C, 15.0g (100mol) of phenyl glycidyl ether (referred to as "PGE" for short) was added dropwise therein for 10 minutes. ). After completion of the dropwise addition, the mixture was stirred at this temperature for 5 hours, and then returned to room temperature over about 10 minutes. Part of the reaction solution was taken, and 1,3,5-trichlorobenzene was used as an internal standard, and quantitative analysis was carried out by gas chromatography. The raw material PGE was almost completely consumed, and the target acetic acid 1,3-diphenoxy-2-propane The yield of the ester was 95% (based on PGE), and the reaction proceeded almost quantitatively. The reaction solution was directly added to the chro...
Embodiment 102
[0240] Except using equimolar tris(2,4,6-trimethoxyphenyl) phosphine (abbreviated as "TMPP") instead of 2,6-DMPP in Example 101, the others were completely reacted as in Example 101 . As in Example 101, the raw material PGE was almost completely consumed, and the production yield of 1,3-diphenoxy-2-propyl acetate was 97%, and the isolated yield was 91%. The catalytic activity is very high, reaching 20mol / mol·h.
Embodiment 103
[0260] In addition to using equimolar tris (2,4-dimethoxyphenyl) phosphine instead of 2,6-DMPP in Example 101, the other reactions were exactly the same as in Example 101, and the target acetic acid 1,3-di The yield of phenoxy-2-propyl ester was as high as 95%, and the isolated yield was 89%.
