Ethylene iminocarbonate

Flynn and Michl have recently succeeded in synthesizing ethylene iminocarbonate (149), which is converted into the trimer (ISO) at room temperature (74JOC3442). 

A number of cyclic monomers containing the imino ether linkage N = C(R)—O— have been successfully polymerized by the ring-opening mechanism. Particularly the derivatives of 2-oxazoline (OXL) u and 5,6-dihydro-4H-l,3-oxazine (OXZ) ° but also 2-iminotetrahydrofuran (ITH)2) and ethylene iminocarbonate (EIC)3> have been studied ... 

The latter polymerization route is also taken by ethylene iminocarbonates (X = O), whereas 2-iminotetrahydrofurans (X = CH2) convert to polyamides ...
