Abstract
Pentacarbonyl-chromium- and -tungsten-co-ordinated thio- and seleno-aldehydes and selenoketones, respectively, react with 1-diethylaminoprop-1-yne via regiospecific [2 + 2] cycloaddition and stereospecific electrocyclic ring-opening to give metal-co-ordinated thio- and seleno-acrylamide derivatives which can be cleaved almost quantitatively from the metal by CO (100 atm.).Keywords
