Related Products of 81606-79-3, New Advances in Chemical Research in 2021. Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 81606-79-3, name is 2-(1,2,4-Triazol-1-yl)acetonitrile, molecular formula is C4H4N4, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
To the solution of 3-[2-[tert-butyl(dimethyl)silyl]oxyethyl]benzaldehyde (1223. OOmg, 4.62mmol) , Toluene (2.5mL), Triethylamine (L95mL, l3.87mmol) was added 2-(lH- l,2,4-Triazol-l-yl)acetonitrile (874.9lmg, 8.09mmol) . The resulted mixture was microwaved at 150 degrees for 3 h. LCMS was shown some product and still had some remained starting material. The reaction mixture was worked up with water (50 mL) and DCM (50 mL x 2). The organic layer was brined and dried with MgS04. The concentrated crude was purified by prep HPLC Shimadzu to obtain 3-[3-[2- [tert-butyl(dimethyl)silyl] oxycthy I ] phenyl ] -2-( 1 ,2,4-triazol- 1 -yl)prop-2-enenitrile ( 120.00mg) with 7.3 % yield. LC-MS m/z: 355[M+l]
