Technology Process of pyridine TFA

There total 4 articles about pyridine TFA which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 88.0%

pyridine (110-86-1) + trifluoroacetic acid (76-05-1) → pyridinium trifluroacetate (464-05-1)

Guidance literature:

In diethyl ether;

DOI:10.1016/j.ica.2010.11.022

Reference yield: 88.0%

pyridine (110-86-1) + trifluorormethanesulfonic acid (1493-13-6) → pyridinium trifluroacetate (464-05-1)

Guidance literature:

In water; at 0 ℃;

DOI:10.1039/c2cc36367d

Reference yield:

(but-3-enyl)bis[dimethylglyoximato(1-)](pyridine)cobalt(III) (36630-46-3) + trifluoroacetic acid (76-05-1) → cis-bis(butane-2,3-dione dioxime)bis(trifluoroacetoxy)cobalt(II) + pyridinium trifluroacetate (464-05-1)

Guidance literature:

In chloroform-d1; allowing soln. of greatest (total tfa)/(total Co) to stand either in diffuse daylight or in the dark at room temp. for 1-2 d; crystals filtered off, washed with cold solvent and hexane, air-dried, dried in vac. at 10-12 mmHg for a few hours;
