Abstract
N-alkynyl aminocarbene complexes 15d and e derived from piperidin-2-one, 15 f and g and from azepan-2-one yield, upon thermolysis, functionalized quino lizines 16-18d,e and homoquinolizines 16-18f,g as the result of a triple-bo nd insertion. a carbon-hydrogen bond activation, followed by a CO insertion . No reaction was observed in the case of complexes derived from pyrrolidin -2-one.
