Ring closure reactionsO 0130 Competition Studies in Alkyne Electrophilic Cyclization Reactions. — The out-
come concerning the ring closure of diarylalkynes is dependent on several factors. The nucleophilicity of competing functional groups, steric nature of substituents, polariza-tion of the alkyne bond, and cationic nature of the intermediates play an important role. — (MEHTA, S.; WALDO, J.
