제목 Silica-Supported Ionic Liquid Containing Selenium Species for Oxidative Carbonylation of Amines to Urethanes
초록 Organic isocyanates (R–NCO) have achieved great commercial importance as chemical intermediates in the manufacture of many useful chemicals. Synthesis of isocyanate via a phosgene-free route has attracted much interest to researchers due to the drawbacks originated from phosgene. Preparing isocyanate by a decomposition method from carbamate is commended as a promising way among the reported non-phosgene routes. As a simplest aryl carbamate, Methyl N-phenyl carbamate (MPC) has been prepared through various methods such as oxidative carbonylation of aniline, reductive carbonylation of nitrobenzene, alcoholysis of 1,3-diphenyl urea, methoxy carboxylation of aniline, and reaction of aniline with methyl carbamate.
In this research, we synthesized silica-supported ionic liquid containing selenium species and applied it for the oxidative carbonylation of aniline to MPC.
