✦ Synopsis

Terminal alkynes with secondary amines idimethylamine, diethylamine, piperidine, morpholine) and CO 2 in the presence of mononuclear ruthenium catalysts, afford the vinyl carbamates RICH=CH-O-CONR2. The reaction studies suggest, as the active catalytic species, a ruthenium-vinylidene intermediate.

## Abstract A highly regioselective intermolecular cyclotrimerization of terminal alkynes has been developed based on the use of the cationic rhodium(I)/DTBM‐Segphos complex. This method can be applied to a variety of terminal alkynes to provide 1,2,4‐trisubstituted benzenes in high yield and with
