a) The process of cyclizing, of becoming or causing to become aromatic.

"The dehydrogenation reactions may involve isomerization and cyclization as well as the formation of olefins and unsaturated compounds generally."

b) Any reaction that results in the formation of a ring.

"It is convenient to run the cyclizations at a temperature between 25° C. and 100° C."
