Triethyl orthoformate yog cov organic sib xyaw nrog cov mis HC (OC2H5) 3. Nws yog cov kua uas tsis muaj xim tsis haum. Nws yog orthoester ntawm formic acid. Muaj kev lag luam, kev tsim khoom lag luam yog los ntawm hydrogen cyanide thiab ethanol.

Nws kuj tseem yuav npaj los ntawm cov tshuaj tiv thaiv sodium ethoxide thiab chloroform:

CHCl3 + 3 Na + 3 EtOH → HC (OEt) 3 + 3⁄2 H2 + 3 NaCl

Triethyl orthoformate yog siv hauv Bodroux-Chichibabin aldehyde synthesis, piv txwv li:

RMgBr {{0}} HC (OC2H5) 3 → RC (H) (OC2H5) 2 + MgBr (OC2H5) RC (H) (OC2H5) 2 + H2O → RCHO + 2 C2H5OH.

Hauv kev sib koom ua ke tshuaj, nws tau siv los hloov cov hlau aquo complexes rau cov sib xyaw ethanol sib xws:

[Ni (H2O) 6] (BF4) 2 + 6 HC (OC2H5) 3 → [Ni (C2H5OH) 6] (BF4) 2 + 6 HC (O) (OC2H5) + 6 HOC2H5
