Article abstract of DOI:10.1021/jo00335a021

A simple one-step synthesis of triptycene analogues prepared by reaction of a diaryne equivalent with anthracenes is described.For example, 1,2,4,5-tetrabromobenzene, anthracene, and n-butyllithium gave 5,7,12,14-tetrahydro-5,14<1',2'>:7,12<1'',2''>-diben
