Abstract

2-Ynamides can be synthesised through Pd(II) catalysed oxidative carbonylation, utilising low catalyst loadings. A variety of alkynes and amines can be used to afford 2-ynamides in high yields, whilst overcoming the drawbacks associated with previous oxidative methods, which rely on dangerous solvents and gas mixtures. The use of [NBu4 ]I allows the utilisation of the industrially recommended solvent ethyl acetate. O2 can be used as the terminal oxidant, and the catalyst can operate under safer conditions with low O2 concentrations.
