Photochemical Reaction of Chromium-Carbene Complexes with Olefins and Dienes: A Comparison with the -Cycloaddition of Ketenes
Koebbing, Stephan,Mattay, Jochen
, p. 927 - 930 (1992)
Described is the preparation of cyclobutanones via the -cycloaddition of ketenes with olefins and the photolytic reaction of chromium-carbene complexes with olefins and dienes.A comparison of these two methods is reported. Key Words: Chromium-carbene
