Cyclization of 1-phenyl-2-propen-1-ones into 1-indanones using H-zeolite and other solid acids. The role of mono- and dicationic intermediates
Cyclization of aryl vinyl ketones into 1-indanones was previously known to proceed only in drastic acidic or superacidic conditions due to the necessity of dicationic, superelectrophilic activationExpand
